Question

An athlete covers a distance of 1200 m in 4 min 48 second . Find the speed in km / hour
​

Answer 1

Step-by-step explanation:

Speed = 14.976 km/hr.

Solution:

Distance = 1200 meter

Time = 4 min 48 sec = 288 seconds

Speed = Distance / Time

Speed = 1200 / 288 = 4.16 m/sec

To convert speed from 4.16 m/sec in to km/hr we have to multiply with 18/5,

4.16 * 18 / 5 = 14.976 km/hr.

Answer 2
