Question

Aakshi ran 500 meter in 100 sec.Find her speed in km per hour.​

Answer 1

Answer:

We can use formula for speed which is dis/time. 500/100 =5m/s.

And we convert it into km/hr. by multiplying from 18/5 so we will get 18km/hr. answer

Answer 2

speed = distance/ time

speed= 500/100

= 5 m/s

In km per hour ,

1km = 1000m

1m=1/1000km

and, 1 hour= 3600 sec

1sec= 1/3600 hours

500/100*3.6

= 18 km per hour
