Question

a cyclist rides for 2 miles, stops for a break, and then rides 2 more miles even faster than before. how long was the cyclists break? 30 minutes 60 minutes 20 minutes 10 minutes

Explanation:

Step1: Analyze the graph

The horizontal line segment in the graph represents the break (no change in distance).

Step2: Calculate the time duration of the break

The start - time of the break is at 20 minutes and the end - time is at 30 minutes. Using the formula \(t = t_{end}-t_{start}\), we have \(t=30 - 20=10\) minutes.

Answer:

10 minutes
