Question

11) If it takes 10 minutes to travel from point

A to point B at a constant speed of 30 miles per
hour, how many minutes does it take to travel
the same route from point A to point B at a
constant speed of 20 miles per hour?

Answer 1

15 minutes

be careful with units!!

10 minutes = 1/6 hour

1/6 hour x 30 miles per hour = 5 miles

5 miles / 20 mph = .25 hour = 15 minutes
