Problema Solution
A backpacking club can average 2 1/2 miles per hour. At that rate, how long will it take for a hike of 8 3/4 mile?
Answer provided by our tutors
since the average rate = the total distance / the total time or
v = d/t, where v = the rate, d= distance, t = time
t = d/v
v = 2 1/2 miles per hour = 2.5 miles per hour
d = 8 3/4 miles = 8.75 miles
t = 8.75/2.5
t = 3.5 hours
it takes 3.5 hours to do the hike.
