Question 21
Megan was walking along a straight road. She met an oncoming car and asked its driver, “Did you overtake a cyclist just now?” “Yes, 10 minutes ago,” replied the driver. After walking for another 10 minutes, Megan met the cyclist. The cyclist’s speed was 4 times Megan’s walking speed. How many times Megan’s speed was the car’s speed?
Assume all three continue at constant speeds without stopping; the car and cyclist travel in the same direction, opposite to Megan.
