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?
Answer & explanation
Correct answer: option 4
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
