Question

if Abhishek Travels at a speed of 25 km per hour in his car he reach office 4 minutes late if he drives at a speed of 30 km I reach office 10 minutes find the distance between his office and his home

Answer 1

Ans: 35 km

Let the time taken to office be x km

Time taken if he drives at 25 kmph = x/25 hr

Time taken if he drives at 30 kmph = x /30 hr

Difference of time = 4 min + 10 min = 14 min = 7/30 hr

x/25 - x/30 = 7/30

30x-25x = 175

5x = 175

x = 35 km

i.e. distance to office = 35 km
