During the winter, a child slides down a steep, icy hill on his sled. If he accelerates at 4 m/s/s, how will it take him to accelerate from 4 m/s to 16 m/s?

the answer is b.)

< 1=< 2

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

not sure but it may be b, as i said i'm not sure.
