Dinesh go to school by cycle at a rate of 18 km/hr. he let by 1 minutes.Howeverf, if he go by scooter at a rate of 28 km/hr. he is early by 3 minutes .find the distance between home to school.
Distance = (X Y)/( Y - X ) * (P + Q)
1 minute = 1/ 60 hr.
3 minute = 3/ 60 hr.
= (18 * 28) / (28 - 18) * (1/ 60 + 3/ 60 )
= 504 / 10 * 4 / 60
= 2016 / 600
= 3.36 km.
Distance between home to school 3.36 km
