Answer: Choice A

The average speed the mouse crawls is 1.5 feet every second.

===========================================================

Explanation:

1 minute = 60 seconds

The mouse crawls 90 ft in 60 seconds.

This forms the ratio

90 ft : 60 sec

Divide both parts of this ratio by 60 to get

90/60 ft : 60/60 sec

1.5 ft : 1 sec

telling us that the mouse's speed is 1.5 ft per second, which explains why choice A is the answer.
