How long does it take to drive 91.5 miles traveling 75mph?

Answer 1

You would divide 91.5 miles by 75 miles. You already know that it takes at least an hour because you are traveling farther than 75 miles. 91.5/75=1.22. That means 1 hour and 22/100 of an hour, or 13.2 minutes. You can test this by using fractions:

22/100: 0.22

13.2/60(minutes): 0.22

So you know the minutes answer because it is equivalent to your previous answer. That means:

It takes 1 hour and 13.2 minutes to drive 91.5 miles traveling at 75mph.
