Given :

  • Distance covered by a bus = 126 km
  • Time taken by the bus to cover that distance = 4 hrs

To find :

  • Distance the bus will cover in 40 mins.

Concept :

Here, we have to find the distance the bus will cover in 40 mins. For that firstly, calculate the speed of the bus when the time taken by the bus was 4 hrs while covering 126 km. Then to find that distance we will use the same speed in which the bus was travelling.

Formulae to be used :-

Formula to calculate speed :-

  • Speed = Distance ÷ Time

Formula to calculate distance :-

  • Distance = Speed × Time

Solution :

Speed of the bus :-

Using formula,

★ Speed = Distance ÷ Time

Substituting the given values,

→ Speed = 126 ÷ 4

→ Speed = 31.5

Speed of the bus = 31.5 km/hr.

Distance the bus will cover in 40 mins :-

Firstly, convert the time from mins to hrs.

As we know,

  • 1 min = 1/60 hr

Divide the value by 60 to convert it from min to hrs.

→ Time = 40 mins = 40/60 hr = 4/6 hr = 2/3 hr

  • Time = 2/3 hr

Using formula,

★ Distance = Speed × Time

Substituting the given values,

→ Distance = 31.5 × 2/3

→ Distance = 21

  • Distance the bus will cover in 40 mins = 21 km.
