Two Coast Gaurd cutters are 225 miles apart traveling toward each other, one from the east and the other from the west. The eastbound cutter travels 5 miles per hour faster than the westbound cutter. If the two cutters pass each other after 3 hours, find the average speed of each cutter.
..
west bound speed be x
eastbound speed = x+5
...
they are travelling towards each other.
so effective speed = 2x+5 mph.
..
distance = 225 miles
time = 3 hours
distance/speed = time
225/2x+1= 3
225 = 3(2x+1)
225 = 6x+3
225-3 = 6x
222=6x
/6
37 = x
westbound speed = 37 mph
eastbound is 5 mph more
