Question

What is the average speed? Answer choices:
A)3 miles per hour
B)3/4 miles per hour
C)1 mile per hour
D)2 miles per hour

Answer 1

A, 3 miles per hour. Two half-hours make an hour, so multiply 1.5 by 2 for an answer of 3.

Answer 2

well since you are dealing with 1/2 you would take that number and multiply it by two to get 3. SO, you are going an average of 3 mph
