Question

Tannu is running at the speed of 10KM/h. Find the distance(in'm') travelled by her in 30s

Answer 1

first make 10km/hr in meters

10x1000=10000  m                            (as 1km= 1000meters)

distance travelled in 1hr=10000m

distance travelled in 1 sec=10000/60x60

distance travelled in 1 sec=100/36

distance travelled in 30 sec=100x30/36

total distance travelled in 30 seconds =83.33m    (approx)
