Linear inequality

If a youg man rides his motor-cycle at 25km  per hour, he has to spend Rs. 2 per  km on petrol ; if he rides it at a faster speed of 40 km per hour , the petrol costs increases to Rs. 5 per km. He wishes to spend at most Rs.100 on petrol and wishes to find what is the maximum distance he can travel within one hour . Express this as linear inequality problem and then solve it.

Thanks in advance
