Question

Two Segways head toward each other from opposite ends of a freeway 308 kilometers long. If the speed of the first Segway is 12 kilometers per hour and the speed of the second Segway is 10 kilometers per hour, how long will it take before the Segways pass each other?

Answer 1

d=r*t

308=12t+10t

308=22t

t=308/22

t=14 hours
