The consumption of diesel per hour of a bus varies directly as square of its speed. When the bus is travelling at 70 kmph its consumption is 1 litre per hour. if each litre costs $70 and other expenses per hous is $ 70, then what would be the minimum expenditure required to cover a distance of 700 Km?	Choices:	A) 1000	B) 1500	C) 1240	D) 1630	E) 1400
70 kmph consumption is 1 lt/hr   so 700 km will take 10 hrs and the consumption is 10 lt for entire distance.   1 lt costs $70   so 10 lt costs $700   extra expenses for 1 hr - $70   10 hrs - $700   total expense - $700 + $700 = $1400   Answer : 1400
