**Reiny**, Tuesday, February 2, 2010 at 7:23pmAssume the truck is standing still, then she must travel a total distance of (14+30)ft in 6 seconds

speed = distance/time = 44 ft/6 sec

44 ft/6 sec = 440 ft/60 sec

= 440 ft/min = 26400 ft/hr

= 5 mi/hr

So she must travel 5 mph faster than the truck, which was going at 50 mph

So she will have to travel 60 mph
