Webthe fly have travelled? The easy way to solve this problem is to realize that the bikers are approaching each other at a net speed of 20 mph, so it will take 5 hours for them to meet. During that time the fly is travelling constantly, back and forth, at 20 mph, so in 5 hours it will travel exactly 100 miles, and that is the answer.

The two trains are 50 miles apart, and are approaching each other at a relative speed of 50 mph (25 + 25), so it will take one hour for them to meet. If the bird spends one hour flying at 100 mph, then WebJan 21, 2010 · Let v be the speed of the fly,v_i,the speed of train i and d,the original distance between the trains. Then T=∑_(n=1)^∞ t_n is the total time that the fly flies. ... The problem can be solved much more simpler by using graphs. A plot of d(t) vs t for the trains A and B will be two straight line who intersect at the time and position where ... crypto got
