Question

Mike hiked to a lake in 4.5 hours at an average rate of 3 2 5 miles per hour. Pedro hiked the same distance at a rate of 3 4 5 miles per hour. How long did it take Pedro to reach the lake? Round to the hundredths place.

Answer 1

4.03 hours

Explanation:

Mike hiked to a lake in 4.5 hours at an average rate of 3 2/5

The distance covered can be calculated as follows

= 4.5 × 3 2/5

= 4.5 × 17/5

= 4.5 × 3.4

= 15.3

Pedro hiked the same distance at 3 4/5 miles per hour, Therefore the time in which Pedro reached the lake an be calculated as follows

= 15.3÷ 3 4/5

=15.3 ÷ 19/5

= 15.3 ÷ 3.8

= 4.03 hours
