two bi cyclists, 52 miles apart, begin riding toward each other on a long straight avenue.
one cyclist travels 16 miles per housr and the other 10 miles per hour.
at the same time, spot ( a greyhound),starting at one cyclist, runs back and forth between the two cyclists as they approach each other.
if spot runs 32 miles per hour and turns around instantly at each cyclist, how far has he run when the cyclists meet?
:
Let t = time for the two bikes to meet, write a dist equation; dist = speed * time
16t + 10t = 52
26t = 52
t =
t = 2 hrs for them to meet
:
The dog runs at 32 mph for two hours then.
32 * 2 = 64 mi dist run by the dog
