Question

if a scooterist drives @ 24 kilometre per hour he reaches his Destination 5 minutes late and if he drive at the rate of 30 kilometre per hour he reaches his Destination 4 minutes early find how far is the destination...??

Answer 1

let distance is x and time is t
we know
time =distance/speed

now
x/24=(t+5/60)hour --------(1)
x/30=(t-4/60)hour -------(2)
solve both equation
x=18km and t=2/3 hour =40minutes
hence 18km far is the destination.
