The fuel charges for running a train are proportional to the square of the speed generated in km/h, and the cost is Rs. 48 at 16 km/h. If the fixed charges amount to Rs. 300/h, the most economical speed is (a) 60 km/h (b) 40 km/h 48 km/h (d) 36 km/h

The fuel charges for running a train are proportional to the square of the speed generated in km/h, and the cost is Rs. 48 at 16 km/h. If the fixed charges amount to Rs. 300/h, the most economical speed is 60 km/h (b) 40 km/h 48 km/h (d) 36 km/h

The fuel cost per hour for running a train is proportional to the square of the speed generated in km/h. if the fuel cost is Rs.48/h at 16 km/h . It the fixed charges amount to Rs.1200/h The most economical speed to run the train is:

The fuel charges for running a train are proportional to the square of the speed generated in km per hour and cost Rs 100 per hour at 20km/hr. If the fixed charge amount to Rs. 10,000 per hour, the most economical speed in km per hour is equal to K, then k/50=

The fuel cost per hour for running a train are proportional to the square of the speed generated in km/h. if the fuel cost is Rs . 48 at 16 km/h . It the fixed charges amount to Rs. 1200/h. The fuel cost for the train to travel 500km at the most economical speed is:

The fuel cost per hour for running a train are proportional to the square of the speed generated in km/h. if the fuel cost is Rs . 48 at 16 km/h . It the fixed charges amount to Rs. 1200/h. If the train has travelled a distance of 500km, then the total cost of running the train is given by function:

The fuel cost per hour for running a train is proportional to the square of the speed it generates in km per hour. If the fuel costs ₹ 48 per hour at speed 16 km per hour and the fixed charges to run the train amount to ₹ 1200 per hour Assume the speed of the train as v km/h. Given that the fuel cost per hour is k times the square of the speed the train generates in km/h, the value of k is:

The fuel cost per hour for running a train is proportional to the square of the speed it generates in km per hour. If the fuel costs ₹ 48 per hour at speed 16 km per hour and the fixed charges to run the train amount to ₹ 1200 per hour. Assume the speed of the train as v km/h. The total cost of the train to travel 500km at the most economical speed is:

The cost of fuel for running a bus is proportional to the square of the speed generated in km/h. It cost Rs 48 per hour when the bus is moving with a speed of 20 km/h. What is the most economical speed if the fixed charges are Rs 108 for one hour, over and above the running charges?
