The distance a car travels can be found using the formula d=rxt, where d is distance r is the rate of speed, and t id time. if the car had traveled 120 miles in 3 hours, what is the average rate of speed?

a. 30mph

b. 40mph

c. 60 mph

d. 360mph

The correct answer is B. 40 mph

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance (d) the car traveled = 120 miles

Time (t) of the travel = 3 hours

2. What is the average rate of speed?

Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel

Replacing with the real values, we have:

Rate of speed (r) = 120/3 miles per hour

Rate of speed (r) = 40 miles per hour

The correct answer is B. 40 mph
