Question

at 40 miles per hour, how many minutes would it take to travel 12 miles. show all workings

Answer 1

40 miles per house which is the same as 40 miles every 60 minutes. Therefore, if you travel 1 mile, it is going to take 60/40=1.5 minutes. Travel 12 miles will be 12*1.5=18 minutes.

Answer 2

40 miles = 1 hr (60 min)

 

So, let's figure the logic...

 

20 miles (half of the distance) = 30 min (half the time)

But, we are looking for 12 miles (which will be LESS than 30 min). 

Let's set it up..

 

40 mi = 12 mi

60 min.   X

 

Cross multiply 40x=720

X=18 min
