Jason can travel 24 3/4 miles in 1/2 hour. what is hi average speed in miles per hour?

49 1/2 miles per hour

Step-by-step explanation:

To determine the average speed, we take the miles and divide by the hours

speed ÷ hours

24 3/4 ÷ 1/2

Change the mixed number to an improper fraction

24 3/4 = (4* 24+3)/4 =99/4

99/4 ÷ 1/2

Copy dot flip

99/4 * 2/1

99/2

Change to a mixed number

2 goes into 99   49 times  (49*2 = 98)  with 1 left over

49 1/2 miles per hour
