Answer:
B. 0.075 in
Evan apparently divided by time. He might do that if he were not paying attention to units.
Step-by-step explanation:
The given rainfall rate is ...
... (1.5 in)/(60 s) = (1/40) in/s = 0.025 in/s
To find the rainfall in 3 s, you need to multiply rate by time:
... (0.025 in/s)×(3 s) = 0.075 in
If you keep the rate and time in terms of minutes, then you have:
... (1.5 in/min)×(0.05 min) = 0.075 in
_____
Evan apparently divided, instead. His number is not inches.
... (1.5 in/min)/(0.05 min) = 30 in/min² . . . . not the appropriate units for the problem
