Answer:
4.03 hours
Step-by-step 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
