Question

Aakshi ran 500 metres in 100 seconds. Find her speed in km per hour.
​

Answer 1

Answer:

given = d : 500m

t : 100sec

s : ?

then speed : d/ t

= 500/100

= 5m/s

Answer 2

We know that s = d/t

⇒s = 500/100

⇒s = 5m/sec

Here, we have to convert m/sec to km/hr.

Hence,we have to multiply the answer with 18/5

⇒s = 5(18/5)

⇒s = 18km/hr

Therefore, Her speed is 18km/h
