Question

Craig left his house at noon and drove 50 miles per hour until 3 p.m. Then he drove the next

5 hours at 70 miles per hour.
Graph Craig’s driving trip and calculate the average rate of change for the entire trip

Answer 1

62.5 mph

Explanation:

rate * time = distance

50 * 3 = 150 mi

70 * 5 = 350 mi

total miles = 500 mi

total time = 8 hrs

Average = 500 mi / 8hr = 62.5 mi / hr
