Answer:
The rate of one is 2.1 mph and the rate of the other is 4.9 mph
Explanation:
Let the rate of one be y mph
The rate of the other = (y+2.8) mph
Total rate = y + y + 2.8 = (2y+2.8) mph
Total rate = distance apart/time
2y + 2.8 = 14/2
2y + 2.8 = 7
2y = 7 - 2.8
2y = 4.2
y = 4.2/2 = 2.1 mph
The rate of the other is y+2.8 = 2.1+2.8 = 4.9 mph
