Question

A man is running in a race at a speed of 180km/hr. Find the distance in km covered in 30 seconds

Answer 1

1hr = 3600 secs
3600sec = 180km
1sec = 180/3600km
30sec = 180*30/3600 km
=1/2 km

Answer 2

Solution:-

man running speed = 180km/h

= 180×5/18 = 10×5 = 50m/s

man covered distance in 30 secound = 30×50

= 1500m = 1.5km
