Explanation:

Step1: Recall speed formula

Speed = $\frac{\text{Change in Distance}}{\text{Change in Time}}$

Step2: Calculate change in distance and time

Change in distance from $t = 0$ to $t = 1$ is $80 - 20=60$ miles, change in time is $1 - 0 = 1$ hour.

Step3: Calculate speed

Speed = $\frac{60}{1}=60$ miles per hour.
