Question

can someone figure this out and show or explain the work...problem..rebecca and her family are going on a trip. they live 180 miles from the Mission. If they travel at an average speed of 53 mph and make only one 40 minute stop, how long will take them to get to the Mission? I set it up like this...53x(t)-40=180.

Answer 1

Let's cheat a bit and say they make their 40 minute stop right at the beginning, how would you do it then?

Answer 2

okay.probably. -40(t)x53=180.

Answer 3

I think you are trying to follow some sort of formula that I don't know about.

The simple way just to answer the question is to say I have 180 miles to go and I can make 53 miles in 1 hour.

So the whole trip will take 180/53 hours plus the 40 minutes (2/3 hours).

Putting it in math, 53*t = 180 and then adjust for your 2/3 hours.

Answer 4

ok. yes that does make sense. the 40 minute stop is what i was figuring in the equation. still have to. thank you.

Answer 5

Remember it has to be in hours....

Answer 6

I'm not sure precisely what you mean by including the stop.

The total time t = 180/53 + 2/3 (in hours).

So just rearrange that into whatever form suits you.
