Question 620727
Mr X Reaches to his office 6 min earlier with a spd of 30km/hr.
And if they drive 24km/hr then there is a delay of 5 min.
Find out the distance of office from his house.
20km 24km 21km 22km
**
let x=time of travel(min)
distance=speed*travel time
30*(x/60)=24(x+11)/60
30x=24x+264
6x=264
x=44min
distance=30*(44/60)=22
distance of office from his house=22 km
