The formula d = rt gives the distance traveled in time t at rate r. A delivery truck drives for 1.5 hours and travels 76 miles.
What was the average speed of the truck?
Question 2 options:
74.5 miles per hour
38 miles per hour
50.7 miles per hourr
114 miles per hour
To find the average speed of the truck, we need to use the formula d = rt and solve for r (rate):
d = rt
76 = r * 1.5
Divide both sides of the equation by 1.5:
76/1.5 = r
r ≈ 50.7
Therefore, the average speed of the truck is approximately 50.7 miles per hour.
