Two drivers, alison and kevin, are participating in a drag race. beginning from a standing start, they each proceed with aconstant acceleration. alison covers the last 1/4 of thedistance in 3 seconds, whereas kevin covers the last 1/3 of thedistance in 4 seconds. who wins and by how much time? show all steps and the logic to get there.

They arrive at the same time.

Step-by-step explanation:

If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.

On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it  means that in 12 seconds will cover three thrds.

Finally we can conclude that both of them spend the same time to cover the drag race.

a=-26,b=-10,c=-1,d=-2

Step-by-step explanation:

when x=-3

y=-(-3)^2 +4(-3)-5=a

a=-9-12-5

=-14-12

=-26

when x=-1

y=-(-1)^2 +4(-1)-5=b

=-1-4-5

b=-10

when x=2

y=-(2)^2 +4(2)-5=c

=-4+8-5

=-9+8

c=-1

when x=3

y=-(3)^2 +4(3)-5=d

=-9+12-5

=-14+12

d=-2
