Since the question is asking for the amount per minute, and there are 60 minutes in an hour, you would divide 75/60.
75/60= 1.25, and that's in kilometres.
Now, we need to convert kilometres into meters, by multiplying it by 1000. We multiply it by 1000 because 1000 meters = 1 kilometre.
1.25 x 1000 = 1250.
Therefore, your answer is 1250 meters per minute.
