Question:-

Find the distance covered by bike in 4 minutes at a speed of 63km/hr .

Solution :-

Formula :- speed = distance/time

a) speed of bike is 63 km/hr .

we know that

=> 1 hr = ( 60 × 60 ) sec = 3600 sec

=> 1 km = 1000 m

so now

=> 63 km = 63×1000 = 63000 m

here,

=> speed = distance/time

=> speed = 63000/3600

=> speed = 35/2

=> speed = 17.5 m/s

By question we have to find, the distance covered by bike in 4 minutes.

=> 4 minutes =( 4 × 60 )sec = 240 sec

now,

Distance covered by bike in 4 minutes

= 17.5 × 240 = 4200 m or 4.2 km

Hence, 4200 m or 4.2 km distance covered by bike in 4 minutes at a speed of 63km/hr .

i hope it helps you.
