Question

For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. if such a car travels 165 miles in 3 hours, how many miles does it travel in 5 hours?

Answer 1

The car travels 165 miles in 3 hours. It is given that the distance traveled varies directly with the time spent driving (This is so because the car has constant speed). That is

`d=kt`. So we have
`d_1=kt_1,d_2=kt_2`, where
`k` a constant (probably speed). Dividing the equations,

`image`

The distance traveled in 5 hours is
`275 \;miles`
