Find each rate in miles per hour

(separate problems)

Honor jogs 9 miles in 2 1/2 hour

Eli walks 9 inches per second

Answer 1

Honor averages 9 / 2.5 = 3.6 miles per hour

Eli walks 9 x 60 inches per minute
= 9 x 60 x 60 inches per hour
= 9 x 60 x 60 / 12 / 5280 miles per hour
= 0.51 miles per hour
