2 m/s

Explanation:

The distance to school is 14.4 kilometers which are equal to 14400 meters.

Amy takes 40 minutes which are equal to 40 × 60 = 2400 seconds to arrive at school.

Bill takes 40 + 20 = 60 minutes which are equal to 60 × 60 = 3600 seconds to arrive at school.

Amy’s average speed = distance (m) / time (s)

Amy’s average speed = 14400 m / 2400 s = 6 m/s

Bill’s average speed = 14400 m / 3600 s = 4 m/s

How much faster (in meters/second) is Amy’s average speed for the entire trip?

Amy’s average speed - Bill’s average speed = 6 m/s - 4 m/s = 2 m/s
