Question 584858: Two bike riders, Jeff and Nancy, are 25 miles apart, riding toward each other at 10 miles per hour and 15 miles per hour respectively. A fly starts from Jeff and flies to Nancy and then back to Jeff and so on. The fly continues back and forth at a rate of 40 miles per hour until the bike riders "collide" and crush the fly. How far has the fly traveled?

the riders are closing the distance at 25 mph (10 + 15), so it takes them one hr to "collide"

the fly is moving at 40 mph, in one hr it travels 40 mi
