Problema Solution
Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the entire time, how long will it take her to get to the lake?*
Answer provided by our tutors
Let
d = 60 mi the distance traveled
v = 40 mph Rene's average rate
t = the time of the travel
Since average speed = distance/time we have:
v = d/t
t = d/v
t = 60/40
t = 1.5 hr
t = 1 hr 0.5*60 min
t = 1 hr 30 min
Rene needs 1 hour and 30 minutes to get to the lake.
