Answer:
0.8 ft per minute
Step-by-step explanation:
The caterpillar is crawling at 20 ft in 25 minutes.
Now, speed is given as;
Speed = Distance/Time
For unit rate of speed, we have to look for the amount of ft crawled for every 1 minute. Since time is 25 minutes;
Thus, we divide both distance and time by 25 minutes.
Unit rate of speed = 20/25 ft per 25/25 minutes = 0.8 ft per minute
