Question

A TRAIN COVERS 405.25 KM IN 2.5 hrs. FIND its SPEAD IN KM/HR AND MTR/MIN
​

Answer 1

Answer :-

• The speed of train in km/h is 162.1 km/h.
• The speed of train in m/min is 2701.66m/min.

Step-by-step explanation ::

To Find :-

• The speed of train in km/h
• The speed of train in m/min

Solution :-

• The speed of train in km/h,

Given that,

• Distance covered = 405.25 km
• Time taken = 2.5 hours

Therefore, speed is,

As we know that,

Speed = Distance ÷ Time,

=> Speed = 405.25 ÷ 2.5

=> Speed = 162.1 km/h

Therefore, the speed of train in km/h is 162.1 km/h.

• The speed of train in m/min

Given that,

• Distance covered by train = 405.25 km
• Time taken = 2.5 hours,

First, we need to convert kilometres to metre and hour to minutes,

• 405.25km = 405250m
• 2.5 hours = 150 minutes

Therefore, speed is,

As we know that,

Speed = Distance ÷ Time,

=> Speed = 405250 ÷ 150

=> Speed = 2701.66

Therefore, the speed of train in m/min is 2701.66m/min.

Answer 2

Answer:

The speed of train in km/h is 162.1 km/h.

The speed of train in m/min is 2701.66m/min.

To Find :-

The speed of train in km/h

The speed of train in m/min

Solution :-

The speed of train in km/h,

Given that,

Distance covered = 405.25 km

Time taken = 2.5 hours

Therefore, speed is,  

As we know that,

Speed = Distance ÷ Time,

=> Speed = 405.25 ÷ 2.5

=> Speed = 162.1 km/h

Therefore, the speed of train in km/h is 162.1 km/h.

The speed of train in m/min

Given that,

Distance covered by train = 405.25 km

Time taken = 2.5 hours,

First, we need to convert kilometres to metre and hour to minutes,

405.25km = 405250m

2.5 hours = 150 minutes

Therefore, speed is,

As we know that,  

Speed = Distance ÷ Time,  

=> Speed = 405250 ÷ 150

=> Speed = 2701.66  

Therefore, the speed of train in m/min is 2701.66m/min.
