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.
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.

It's 3 3/8 or 27/8 or 3.375

My apologies for the error. You are correct. The average speed is 3 3/8 miles per hour, which is equivalent to 27/8 or 3.375.
