Question

the speed of metro train is thrice as that of a bus find the speed of the bus if the metro covers 120 km in 15 minute.​

Answer 1

Answer:

109.09 (km/hr)

Step-by-step explanation:

According to the given problem,

A bus covers a certain distance at a speed of 120 km/hr in 5 hrs.

Let S denotes the speed at which the bus must travel in order to cover the same distance in [5 (1/2) =] 11/2 hrs.

Hence we get the following relation,

S*(11/2) = 120*5

or S = 1200/11 = 109 (1/11) = 109.09 (km/hr)

Answer 2

Step-by-step explanation:

GIVEN

• Metro Train Speed = Thrice Than The Speed Of Bus

• Distance Covered By Metro = 120 km

• Time In which Distance Covered By Metro = 15 minutes

___________________________

TO FIND

• Speed Of Bus

___________________________

We know that,

• Speed = Distance / Time

Here,

• Speed = ?

• Distance = 120 km

• Time = 15 minutes = 0.25 hours

• Speed = 120 / 0.25

• Speed = 480

• Speed = 480 km/h

Speed = 480 km/h

___________________________

We know that,

• Speed Of Metro = Thrice Than The Speed Of Bus

• 480 = 3 × Speed Of Bus

• Speed Of Bus = 480 / 3

• Speed Of Bus = 160

• Speed Of Bus = 160 km/h

Speed Of Bus = 160 km/h
