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

Vlad [161]

Answer:

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

Step-by-step explanation:

Given that:

Time taken by bus journey = 45 minutes = $\frac{45}{60} = 0.75\ hour$

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 = $\frac{25}{60}\ hour$

Distance = Speed * Time

45 = $\frac{25}{60}*Speed$

Speed = $45*\frac{60}{25}$

Speed = 108 km/h

Hence,

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