Question

Terry usually rides his bike at 15 mph. If his riding speed is reduced by 3 mph, how far can he ride in 1.7 hours? ​

Answer 1

20.4 miles

Step-by-step explanation:

Terry's normal speed while riding his bike =
`15\ \text{mph}`

Speed is reduced by
`3\ \text{mph}`.

So his speed now is
`15-3=12\ \text{mph}`

The time for which the distance needs to be found is
`1.7\ \text{hours}`

Distance is given by

`\text{Distance}=\text{Speed}* \text{Time}`

`\text{Distance}=12* 1.7=20.4\ \text{miles}`

So, the distance traveled in 1.7 hours is 20.4 miles.
