First, we need to get everything in the same units. Because the question asks 'how many minutes' we need to convert the 2hrs and 20mins into all mins. :
1hr = 60mins--->2hrs = 2(60mins) = 120mins
Therefore, 2hrs and 20mins = 120 + 20 = 140mins
If you drive 100 mile in 140 minutes, you get:
100 miles = 140 minutes
1 mile = 140mins/100miles = 1.4mins/mile
Multiply this rate by 10 miles and you get:
10 miles X 1.4mins/mile = 14 minutes
Your answer is 14 minutes!
Hope this helps!
