Ahiker walked 12.8 miles from 9: 00 a. m. to noon. he walked an additional 17.2 miles from 1: 00 p. m. to 6: 00 p. m. what is his average rate for the entire walk, in miles per hour?

Average rate for the entire walk, in miles per hour is the division of total miles walked by total time.

His average rate for the entire walk, in miles per hour is 3.75 miles per hour

Given:

Distance 1 = 12.8 miles

Distance 2 = 17.2 miles

Total distance = Distance 1 + Distance 2

= 12.8 + 17.2

= 30 miles

Time 1 = 9:00 a.m. to noon = 3 hours

Time 2 = 1:00 p.m. to 6:00 p.m = 5 hours

Total time = Time 1 + Time 2

= 3 + 5

= 8 hours

Average rate worked = Total distance ÷ Total time

= 30 miles ÷ 8 hours

= 3.75 miles per hour

Therefore, his average rate for the entire walk, in miles per hour is 3.75 miles per hour
