Question

Kyra drove to visit her friend, covering 125 miles in 3 2/3 hours. What was her average speed?

a. 30 mph
b. 34 mph
c. 40 mph
d. 45 mph

Answer 1

Kyra's average speed was calculated by dividing the distance (125 miles) by the time (3 2/3 hours, or 3.67 hours), resulting in approximately 34 mph, which is option (b).

Step-by-step explanation:

To find Kyra's average speed, we need to divide the total distance traveled by the total time spent traveling. The formula for average speed is Vavg = distance / time. Kyra drove 125 miles in 3 2/3 hours (which is 3.67 hours when converted to decimal form).

Using the formula:

1. Convert the time to hours: 3 2/3 hours = 3 + 2/3 = 3 + 0.67 = 3.67 hours.
2. Calculate the average speed: Vavg = 125 miles / 3.67 hours = approximately 34 mph.

Therefore, Kyra's average speed was around 34 miles per hour, making option (b) the correct choice.
