tom drives at a constant rate of 40 miles per hour for 3 hours.how far will he travel at that time?
A.350 mi.
B.220 mi.
C.120 mi.
D. 60 mi.

Answers

Answer: C. 120 mi.

Step-by-step explanation:

To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!

Answer:

C. 120 mi.

Step-by-step explanation:

If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.
