Question

Mike hiked to Big Bear Lake in 4.5 hours at an average rate of 3 1 _ 5 miles per hour. Pedro hiked the same distance at a rate of 3 3?

Answer 1

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

 

THe distance is 14/4 miles
