Question
A bicyclist rides for $2 \mathrm{h}$ at a speed of $10 \mathrm{mph}$ and then returns at a speed of $20 \mathrm{mph}$. Find the cyclist's average speed for the trip.
Step 1
The distance is calculated by multiplying the speed by the time. In this case, the speed is $10 \mathrm{mph}$ and the time is $2 \mathrm{h}$. So, the distance is $10 \times 2 = 20 \mathrm{miles}$. Show more…

John bikes a distance of 120 miles and then returns over the same route. On his return his average speed is 2 miles per hour more than when going. If the combined time for both trips was 22 hours, what was his speed each way?
