15 mph

Explanation:

Speed can be found using the following formula.

s=d/t

where d is the distance and t is the time.

The car traveled 30 miles in 2 hours. Therefore, the distance is 30 miles and the time is 2 hours.

d=30 miles

t=2 hours

s = 30 miles/2 hours

Divide 30 by 2

s=15 miles/hour

The car's speed is 15 miles per hour.
