A car takes `2` hours to reach a destination by travelling at the speed of `60 "km/h"`. How long will it take when the car travels at the speed of `80 "km/h"`?

Explanation

let distance travelled be `k`

let speed of travelling be `s`

let time taken for `80 "km/hr"` be`x`

so, `t=k/s`

`k = t*s`

acc to question

`=> k =2*60= 80*x`

`x = 120/80`
