Answer:
a) 375 mph
b) 6.25 mi/min
c) 0.16 min/mi
Step-by-step explanation:
To find miles per hour, divide miles by hours:
a) (1875 mi)/(5 h) = 375 mi/h
__
b) You have hours in the denominator, and you want minutes there, so the conversion factor is (1 h)/(60 min):
(375 mi/h)·(1 h)/(60 min) = (375/60) mi/min = 6.25 mi/min
__
c) Minutes per mile is the inverse of the value you just calculated:
1/(6.25 mi/min) = (1/6.25) min/mi = 0.16 min/mi
