Question

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

Answer 1

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

Given:

Distance = 500m

Time = 100 seconds

To find:

The Speed

Solution:

Since distance is 500m, converting it into kms -  

Distance in km =500/1000

= 0.5km

Now since time 100sec, as per hours will be -  

Time in hours = 100/3600

= 0.027 hours

Using the formula of speed -

Speed = Distance/Time

Substituting the values -

= 0.5/0.027

= 18.51

Answer: The speed of Aakshi is 18.51 km/hr
