A car moves a distance of 2592 km with uniform speed.The number of hours taken for the journey is one-half the number representing the speed,in km/hour.Find the time taken to cover the distance.

A train covers a distance of 12 km in 12 minutes, if its speed is decreased by 5 km/h, then the time taken by it to cover the distance of 22 km will be: एक ट्रेन 12 मिनट में 12 किमी की दूरी तय करती है, अगर इसकी चाल 5 किमी/घंटा कम हो जाती है, तो इसके द्वारा 22 किमी की दूरी तय करने में लगने वाला समय होगा:

A person has to cover a distance of 160km in 15 hours. If he covers 4/5 of the distance in 2/3 of the time, then what should be his speed (in km/hr) to cover the remaining distance in remaining time ? एक व्यक्ति को 15 घंटे में 160 किमी की दूरी तय करनी होती है। यदि वह 2/3 समय में 4/5 दूरी को तय करता है, तो शेष समय में शेष दूरी को तय करने के लिए उसकी चाल (किमी/घंटा में) क्या होनी चाहिए?

A car covered 150 km in 5 hours. If it travels at one-third its usual speed, then how much more time will it take to cover the same distance? 5 घंटे में एक कार 150 किमी की दूरी तय करती है। यदि यह अपनी सामान्य चाल से एक-तिहाई चाल से यात्रा करे, तो समान दूरी तय करने में कितना अधिक समय लगेगा?

A train covers 400km at a uniform speed. If the speed had been 10km/h more. It would have taken 2 hrs less for the same journey. What is the usual time taken (in hours) by it to complete the journey ? एक ट्रेन एक समान चाल से 400 किमी की दूरी तय करती है। यदि चाल 10 किमी/घंटा अधिक होती तो उसी यात्रा के लिए ट्रेन को 2 घंटे कम लगते । यात्रा को पूरा करने के लिए इसके द्वारा (घंटों में) सामान्य रूप से कितना समय लगता है?

Mohan covers a distance of 2.5 km by scooter at the rate of 30 km/h. The time taken by Mohan to cover the given distance (in minute) is: मोहन ने स्कूटर द्वारा 30 किमी/घंटा की चाल से 2.5 किमी की दूरी तय की। मोहन द्वारा दी गयी दूरी को मिनटों में तय करने का समय (मिनटों में ) है:

Rahul and Mithun travel a distance of 30 km. The sum of their speeds is 70 km/h and the total time taken by both travel the distance is 2 hours 6 minutes. The difference between their speeds is: राहुल और मिथुन 30 किमी की दूरी तय करते हैं। उनकी चाल का योग 70 किमी/घंटा है और दोनों के द्वारा दूरी तय करने में लगने वाला कुल समय 2 घंटे 6 मिनट है। उनकी चाल के बीच का अंतर है:

A person covers 700 m distance in 6 minutes. What is his speed in km/h? एक व्यक्ति 6 मिनट में 700 मीटर की दूरी तय करता है। किमी/घंटा में उसकी चाल कया है?

A car covers 25 km at a uniform speed. If the speed had been 8 km/h more, it would have taken 10 hours less for the same journey. What is the speed of the car (in km/h)? एक कार 25 किमी की दूरी एक समान चाल से तय करती है | यदि चाल 8 किमी/घंटा अधिक होती, तो इसे इस यात्रा में 10 घंटे कम लगते | कार की चाल ( किमी/घंटा में)कितनी है?

A person covers 40% of a distance with a speed of 60 km/h and the remaining with a speed of 40 km/h. What is his average speed for the whole journey in km/h? एक व्यक्ति किसी दूरी का 40% हिस्सा 60 किमी/घंटा की चाल से तथा शेष दूरी 40 किमी/घंटा की चाल से तय करता है | पूरी यात्रा में उसकी औसत चाल ( किमी/घंटा में ) ज्ञात करें |
