suman travel from home for his school at 3 km per hour he reaches school 8 minutes late. if he travels at the rate of 4 km per hour he reachee school 12 minutes early. find the distance between his school and home?​

Answer 1

Answer:

Let the distance between school and home be x km.

The difference of time when he goes to school with these two different speed is 10 min = 10/60 hour.

Now,

(x/3)-(x/4)= 10/60

Or, x/12 = 1/6

Or, x = 12/6

= 2 km.
