A

Step-by-step explanation:

We need to use the distance-rate-time formula here: , where d is distance, r is rate, and t is time.

Here, the distance traveled is actually m, while the rate is 45 and the time is h. So, just plug these in:

Thus, the answer is A.

Hope this helps!

Step-by-step explanation:

Speed = distance/time

45 = M/h

M = 45h
