Answer 1

Answer

30

Step-by-step explanation:

Let distance between house and office  = x km

Time taken if he moves with a speed of 30 km/hr  = x /30 hr

Time taken if he moves with a speed of 40 km/hr  = x /40 hr

Difference in time  = x /30 − x /40

But the difference in time = (10 min + 5 min) = 15 min =  1 /4 hr

Therefore,

x /30 − x /40 = 1 /4

4 x − 3 x = 30

x = 30
