Question

(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same

journey in 25 minutes? plzz answerr!!!​

Answer 1

The car must drive at 108 km/h to cover the same journey.

Explanation:

Given that:

Time taken by bus journey = 45 minutes =
`(45)/(60) = 0.75\ hour`

Speed of bus = 60 km/h

Distance of the journey = Speed * Time

Distance of the journey = 60 * 0.75 = 45 km

The car needs to cover 45 km in 25 minutes.

25 minutes =
`(25)/(60)\ hour`

Distance = Speed * Time

45 =
`(25)/(60)*Speed`

Speed =
`45*(60)/(25)`

Speed = 108 km/h

Hence,

The car must drive at 108 km/h to cover the same journey.
