Question

Explanation:

Step1: Calculate the rate of climbing

First, find the rate of climbing today. Rate = $\frac{\text{Number of stairs}}{\text{Time}}$. So the rate $r=\frac{1000}{25}=40$ stairs per minute.

Step2: Calculate the time for tomorrow

Tomorrow he will climb 280 stairs. Using the formula Time = $\frac{\text{Number of stairs}}{\text{Rate}}$. So the time $t = \frac{280}{40}=7$ minutes.
