distance between two stations is 144 km. Find the speed of the train. A
A train leaves New Delhi at 1915 hours and arrives Mathura at 2205 hours. The​

Answer 1

Answer:

1) Assuming uniform speed, 950 m is covered in 5 minutes.

Thus the speed is 950 m / 5 min = 190 m/ min.

You asked for speed in km / hr .

1 km = 1000 m and 1 hr = 60 min.

Let us go one step at one time.

So if the cyclist covers 190 m / min, then in 60 minutes he will travel 190*60 = 11,400 m per 60 minutes.

11,400 m/60 minutes = 11,400 m/ hr because 11,400 m = 11.400 km.

Thus, speed in km/ hr = 11.400 km/ hr.

Hope you got this conversion.

For a quick conversion in one step remember to divide the m/min speed by 16.666 (which is 1000/60 ) to get the km/ hr speed.

2) Distance travelled: 144 km

=144*1000

= 144000 metres.

= 144000/10200.

Speed=14.117 m/s.

= 50.82 km/hr.
