Question

John walked 4 1/2 miles on a park trail in 1 1/3 hours what was her average speed in miles per hour

Answers

GPT 3.5
To find the average speed, we need to divide the total distance traveled by the total time taken.

Total distance = 4 1/2 miles
Total time = 1 1/3 hours

To add 1/3 to 1, we need to find a common denominator. The common denominator for 1 and 3 is 3.

1 1/3 = 3/3 + 1/3 = 4/3

Total time = 4/3 hours

Average speed = Total distance / Total time
Average speed = 4 1/2 miles / 4/3 hours

To divide a fraction by another fraction, we need to multiply the first fraction by the reciprocal of the second fraction.

Average speed = 4 1/2 miles * 3/4 hours
Average speed = 4 * 3/2 * 4/3 miles/hour
Average speed = (4 * 3)/(2 * 4) miles/hour
Average speed = 12/8 miles/hour
Average speed = 3/2 miles/hour

Therefore, John's average speed was 3/2 miles per hour.
