Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Ex: If the input is:

20.0 3.1599 

Then the output is:

1.579950 7.899750 63.198000 

Note: To solve the problem, calculate first the gas cost for driving a mile. Then use this result to compute the gas cost for 10 miles, 50 miles, and 400 miles.

Note: Real per-mile cost would also include maintenance and depreciation.

Note: Output appears on one line
