The distance travelled by a person varies directly with the duration of the journey. If the person travels 378 km in 7 hours, in how many hours will the person cover 918 km?

17

We know ,

Speed = \(\frac{Distance}{Time}\)

Speed= \(\frac{378}{7}\) = 54 km/h

Time to cover 918 km ,

Time = \(\frac{Distance}{Speed}\)

= \(\frac{918}{54}\)

= 17 hours
