To determine the average speed of the mouse, we first need to convert the distance and time into consistent units. The mouse crawls 90 feet in 1 minute.

1 minute = 60 seconds, so:

- Speed = distance / time = 90 feet / 1 minute
- Convert 1 minute to seconds: 1 minute = 60 seconds
- Speed = 90 feet / 60 seconds = 1.5 feet per second.

Now, let's evaluate the options:

A. The average speed the mouse crawls is 0.66 feet in 1 minute. (Incorrect)
B. The average speed the mouse crawls is 0.11 feet every second. (Incorrect)
C. The average speed the mouse crawls is 0.66 feet every second. (Incorrect)
D. The average speed the mouse crawls is 1.5 feet every second. (Correct)

Therefore, the true statement is:
**D. The average speed the mouse crawls is 1.5 feet every second.**
