Question

During a thunderstorm, 600 millimeters of rain fell in 30 min.

A. How fast did the rain fall, in millimeters per minute?

B. How fast did the rain fall, in millimeters per hour?

C. Which unit rate do you think is more useful? Explain your reasoning.

Sorry that I can only put 10 points. But please I really need help with this

Answer 1

A: 600/30 = 20mm/min

B: 1200 mm/hr (double the 30 min amount)

C: I think mm/hr is more useful because the actual rainfall can vary a lot from minute to minute. Looking at the amount over an hour averages that out.
