Question

Mohan walks from his house at a speed of 5 kmph,

speed and reaches his office 10 minutes late. If his

speed had been 5 kmph he would have reached 10

minutes early. What is the distance to his office

from his house?​

Answer 1

Answer:

Let the actual time be 't'

and distance be x

Now according to first condition, we have

4

x

=t+

60

5

And according to Second condition, we have

5

x

=t−

60

10

60x=4t+20

60x=5t−50

Subtracting equation 1 from 2, we have

0=t−70

∴t=70

Putting the value of t we get x=5km
