distance = 8m = 8x100 = 800cm
speed = 42/5 cm/s
so, time taken = distance/speed
= 800 x 42/5
= 6720 second
= 6720/60 minute
= 112 minute
= 112/60 hour
= 1 hour 52 minute
speed = 42/5 cm/s
so, time taken = distance/speed
= 800 x 42/5
= 6720 second
= 6720/60 minute
= 112 minute
= 112/60 hour
= 1 hour 52 minute

Sir; time =distance/time
800÷42/5
So =800×5/42== 400×5/21((dividing numerator and denominator by 2)))
= 2000/21 Sec
Ans approximately 1min 35 s
