let exact time required to reach office= x
time taken when Ravi travels with a speed of 5km/hr = x+3 min =x+1/20 hr
distance =5km/hr×x+1/20
time taken when Ravi travels with a speed of 15km/hr = x-5 min =x+1/12 hr
distance=15km/hr×x+1/12
as distance is same
5km/hr×x+1/20=15km/hr×x+1/12
5x+1/20=15x+1/12
