Can you show me how this works out to be?

A man dropped his wife off at the job at 8:50am and was seen at Target at 9:28am walking in the door he left the store with items 10:30am. The question is he had the baby with him and had to drop her off to complete this. How long does it take a man to change his clothes and drop off a baby 20mins away and come back 20mins to Target in between the time frame of 8:50-9:28 How fast had he have to drive on the highway the speed limit is 60mph. Was he also speeding? If you can show me the math and explain it the 10pts are yours to have.Can you show me how this works out to be?
Too bad that in paraphrasing the question you have garbled it.





With the information provided your question is:





1) Impossible to do, impossible to answer. If two 20 minute trips must occur (as specified in the question), then a total of 40 minutes must pass between dropping the wife off and arriving at the store. Since 8:50-9:28 is only 38 minutes, it is impossible to accomplish and impossible to solve. The question is bogus unless one accepts outside forces are involved aka time travel, wormholes, time zones.





2) Possible to do impossible to answer. If two 20 mile trips are involved then it becomes physically possible to accomplish, but impossible to answer due to variables in the speed driven, and the amount of time to drop off the baby, and the time to change clothes, and the time it takes to park and walt into the store. Unless there is other info not given in your question!


Examples:


He could have driven ar 120 mph, there and back., and had 18 minutes to drop the kid off/change clothes.


He could have driven at 119 mph, there and back and had 17.5 minutes to do business at home.


And so on down to about 64 mph, whereby he tosses the kid out the window as he sped past his home.





3) Incomplete. Does the original question simply mention that the home is 20 minutes away and that the had to drop off the baby? Thus, you assume he is required to drive home and back again, whereas he may have driven 10 minutes to the baby sitter/daycare. You also assume that there is only one Target store involvedCan you show me how this works out to be?
Try using enough grammar to make the question intellegable. Then maybe I'll answer it.
Could you rephrase the question? A little vague.
its impossible unless he has a wormhole cause without the trip it ends up being till 9:30 a.m. if ur in skewl then do that 0 with the slash in it.
that uis imposible because u made tyhat question up he had tha total of 40 min and every thing he had to do took a least 70 mn.
There is nothing in the statement of this question that says the wife's workplace and the Target are in the same time zone.


He dropped off his wife in one time zone and the changed clothes, dropped off the baby and went to Target in another time zone.


He had 98 minutes to get from his wife's workplace to Target.
Go do your homework, Dudette!
Well, he had 38 minutes to get from his wife's job to Target. If it was 40 miles roundtrip to the place where he dropped off the baby, then he had to be speeding to do that, even if he didn't change clothes.





(1 mile = 1 minute at 60 mph)
I am not posative but i think this is unsolveable. 8:50 and 9:28 is 38 minutes, imposible to find out the speed of travel as well. Or i am really bad at mathmatical equations, who knows.
Dropped her off at 8:50...add 20 minutes to baby drop off and clothes change = 9:10 (9:20 to include clothes changing), add 20 minutes to get back to Target = 9:40....hmmm, good question. then again, if he sped a little bit (which we all do...so he probably did 70 in a 60) he could have shaved a mere 5 minutes off each way, which explains why he got there roughly 9:30, instead of 9:40. There probably is a way to put it all down mathematically, but I think you have to be somewhat of a mathematician to do that.
