"When we do experiments it's a good idea to do multiple trials, that is, do the same experiment lots of times. When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events. Multiple trials can be done at one time."

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
