You can put this solution on YOUR website! A distance of 33 KM is covered in 1 hr. 12 minutes. If the first 15 KM is covered at the speed of 25 KM per hour. Find the speed during the remaining distance.
***l
let x=travel time for first 15 km
travel time=distance/speed
x=15 km/25 km/hr
x=(15/25)=(3/5)hr=36 min
..
1 hr 12 min=72 min
72-36=36=travel time of remaining distance
remaining distance=33-15=18 km
speed=18/(36/60)=30
speed during the remaining distance=30 mph
