A man drives fom the origin to his destination in his car at the speed of 24km/hr and reaches 5 minutes late.Next day he drives from the same origin to the same destination with a speed of 30km/hr and reaches 4 minutes early.Find at what distance is the origin from the destination.Write a linear equation using the given information.

time difference is 9 minutes = 9/60 hr
the distances are the same
time = distance/speed
d/24 = d/30 + 9/60
d = 18
check:
18/24 = 3/4 = 45 min
18/30 = 3/5 = 36 min
