Question

Geeta is going on her moped at a speed of 24 km/h.How much time will she take to cover 540 metres?

Answer 1

Answer:

speed = 240 km/hr

Convert it into m/s by multiplying 5/18

240 x 5/18

= 6.6 m/s

WE KNOW THAT..

SPEED = DISTANCE /TIME

THEREFORE TIME = DISTANCE/SPEED

=540/6.6

=81.81 sec

Therefore she will take 81.81 sec to cover 540metres at the speed of 24 km/hr

Answer 2

Answer:

Given -:

Speed = 24km/hr

Distance =$\frac{540}{1000}$km

= $\frac{27}{50}km$

Time taken

= $\frac{Distance in km}{Speed in km/hr}$

= $\frac{27}{50×24}$

= $\frac{27×60}{50×24}$ min

= $\frac{27}{20}$min

= 1min 21sec
