Question

question 11 of 25. a truck driving east on a highway goes from the 42 mi marker to the 48 mi marker in 5.0 minutes. what is the trucks average velocity during this time? a. 1.2 mi/min east b. 30 mi/h east c. 9.6 mi/min east d. 0.83 mi/min west

Explanation:

Step1: Calculate displacement

$\Delta x = 48\ \text{mi} - 42\ \text{mi} = 6\ \text{mi (east)}$

Step2: Compute average velocity

$v_{\text{avg}} = \frac{\Delta x}{\Delta t} = \frac{6\ \text{mi}}{5.0\ \text{min}} = 1.2\ \text{mi/min (east)}$

Answer:

A. 1.2 mi/min east
