slower faster in the same amount of time
I gave my students this multiple choice question: Base your answers on the information below. One hot, summer day it rained very heavily. After the rain, a plastic pan on a picnic table had 2 cm of rainwater in it. Four hours later, all the rainwater in the pan was gone. If the day were cool instead of hot, the rainwater in the pan would have disappeared

Only one answer is correct among these 4 choices:
- slower
- faster
- in the same amount of time

Could you tell me which one is correct?

slower
