Question

Kadeem and Quinn both drive 25 miles. Kadeem drives at a constant speed of 50 miles an hour. Quinn drives at a constant speed of 75 miles per hour. Who takes longer to drive 25 miles? How much longer?

Answer 1

Kareem takes longer to drive the 25 miles. Kadeen takes 10 minutes longer than Quinn.

Explanation:

The formula for time is distance over speed (distance/speed)

Kadeem

distance/speed = 25/50 = 1/2 hour = 30 minutes

Quinn

distance/speed = 25/75 = 1/3 hour = 20 minutes
