taylor rode a scooter from home to the pizza place at an average speed of 6 miles per hour, and then rode a scooter back the same way at an average speed of 15 miles per hour. if the round trip took 2 hours and 45 minutes, how many miles is taylor's one-way trip from home to the pizza place?
Answer provided by our tutors
let
d = miles from home to the pizza place
v1 = 6 mph the average speed to the pizza place
v2 = 15 mph the average speed back
t = 2 hr 45 min = 2 + 45/60 = 2.75 hr
since v = d/t follows t = d/v
d/v1 + d/v2 = 2.75
d/6 + d/15 = 2.75
by solving we find:
d = 11.79 mi
