Multiple Choice

It takes Natalie 0.25 hours to drive to school. Her route is 16 km long. What is Serina’s average speed on her drive to school?

• 1 km/h

• 4 km/h

• 64 km/h

• 64 mph

Correct Answer : 64 km/h

If it takes Natalie 0.25 hours (time) to drive 16 km (distance), to find the speed you would have to divide the distance by the time.

S = D / T

S = 16 km / 0.25 hours

S = 16/0.25 = 64 (now add your units of measure)

S = 64 km/h

HAVE A GREAT DAY!!!
