Question 763152: a road is 300 miles long. A car, A, starts at noon from one end and goes throughout at 50 mph, and at the same time another car, B, going uniformly at 100 mph, starts from the other end together with a fly travelling 150 mph. when the fly meets car A, it immediately turns and flies towards B. the fly then continues flying backwards and forward between A and B until it crushed between two cars. What is the total distance travelled by the fly?

Car A travels at 50 mph, Car B at 100 mph.
In one hour, they will come (100+50) i.e. 150 miles closer
Since they are 300 miles apart, the time taken for them to meet = 300/150 = 2 hours
The fly travels at 150 mph, so in 2 hours it will travel (150*2) = 300 miles
So before it gets crushed by the 2 cars, the fly would have travelled miles!
That's a really fast fly :)
