Practice Time and Distance – A person was fined for exceeding the speed limit by 10 km/hr. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35km/hr,find the speed limit.
Practice Time and Distance – It takes 8 hours for a 600 km journey, if 120 km is done by train and the rest by car. It takes 20 minutes more, if 200 km is done by train and the rest by car. The ratio of the speed of the train to that of the cars is:
Practice Time and Distance – A car covers four successive 6 km stretches at speeds of 25 kmph, 50 kmph, 75 kmph and 150 kmph respectively. Its average speed over this distance is
Practice Time and Distance – A man walks at 40kmph and reaches the distance in 10 min less than that of usual. By walking at 60 kmph he reaches 10 minutes earlier. The distance covered by him is?
Practice Time and Distance – Excluding stoppages, the speed of the bus is 54 kms /hr and with stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?
Practice Time and Distance – An athlete runs 200 metres race in 24 seconds. His speed is
Practice Time and Distance – A person walks a distance of 18 kms at a particular speed. For the next 30 kms he increases his speed by 2 kmph. Had he walked the entire distance at 3 kmph more than his initial speed, he would have reached 4 hours earlier. Find his initial speed.
Practice Time and Distance – Excluding stoppages , the speed of the bus is 54 km/hr and including stoppages , it is 45 km/hr . For how many minutes does the bus stop per hour ?
Practice Time and Distance – A car moves at the speed of 80 km/hr. what is the speed of the car in metres per second?
Practice Time and Distance – A man travels by bus for 20 hours and they by train for 05 hours . if the average speed of the bus was 20 kmph and that of the entire journey was 24 kmph. What was the average speed of the train?
Practice Time and Distance – A man driving his bike at 24 kmph reaches his office 5 minutes late. Had he driven 25% faster on an average he would have reached 4 minutes earlier than the scheduled time. How far is his office?
Practice Time and Distance – When a stone is dropped from a building 200 m high, its speed is proportional to the time elapsed after dropping. The distance traveled is proportional to the square of the time elapsed. After 1 second the speed of the train was 10 m/sec and it was 190 m above the ground. When its speed is 25 m/sec, what would be its distance from the ground?
Practice Time and Distance – Distance between 2 places A and B is given. A man P starts from place A at 9 pm and another man Q goes from B at 10pm. Speed of Q is double of that of P. Both cover 1/4 dist in the same time interval. then A travels the entire distance in what time?
Practice Time and Distance – A boy standing idle sounds a whistle to his friend at a distance of 1200 m moving away from him in a speeding car at 108 kms /hr. Find the duration after which his friend is going to hear him. (Speed of sound = 330m/sec).
Practice Time and Distance – An aircraft is flying at a height of 3000m from the ground at an average speed of 400 km/hr while descending. It has to travel 5 kms before it can touch down the runway and start operating its break system. It will take less than 10 seconds to reach the touch down point. How far it is from the touch down point if it had been on they ground.
