Oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
In the first 10 seconds it is 200m
In the next 10 seconds (it is decelerating 2m/s every second) it is 100m
200m+100m=300m
300 meters is the answer
X+y=55
Y= X+17
X+ X+17=55
2x+17=55
Subtract 17
2x= 38
Divide by 2
X=19
Larger number 19+17=36
36
