Question

Mike hiked to a lake in 4.5 hours at an average rate of 4 1/5 miles per hour. Pedro hiked the same distance at a rate of 4 3/5 miles per hour. How long did it take Pedro to reach the lake? Round to the hundredths place.

Answer 1

Answer:

distance = rate x time

3 and 1/5 = 3.2 and 3 and 3/5 = 3.6

distance = 3.2 x 4.5 = 14.4

14.4 = 3.6 x T

T = 14.4 / 3.6 = 4 <--- Pedro's time
