Question 2

In a mile race, Arun runs at a speed of 10 km/hr. he gives a start of 200 metres to Chintu and still defeats him by 24 seconds. Find the speed of chintu.

Question 3

Three athletes run a 5 km race. Their speeds are in the ratio 15 :10 : 8 . When the winner wins the race , then the distance between the athlete in the 2nd position to the athlete in 3rd position is :

Question 4

A train driver leaves Gorakhpur at 6:30 am and expects to reach at place 600 km from Gorakhpur at 2:30 pm. At 12:30 pm he finds that he was covered only 40% of the distance by how much he has to increase the speed of the train in order to reach at the scheduled time?

Question 5

A train after 3 hours from starting meets with an accident which detain it from an hour. After this, the train proceeds at 75% of its former speed and arrives 4 hours late. Had the accidents happened 150 km farther along the line, it would have arrived only  hours late if it travelled with 75% of its natural speed. Find the natural speed of the train and total distance of the journey?
