Question

A car traveled at 65 miles per hour for a total of 390 miles. How many hours did the car travel?

Answer 1

`390 miles / 65mph = 6 hours.`

Answer 2

Formula to calculate it is simple:

`v=(s)/(t)`
where v is the speed, s-road, t-time
Speed ​​is equal to the ratio of road to czau estimated driving:

`65=(390)/(t)|*t`

`65t=390|:65`

`t=(390)/(65)`

`t=6`
The car was for 6 hours.
