Question

Help me solve this pleasee

Answer 1

B. 65 m

Explanation:

`s = (1)/(2) (u + v)t \\ s = (1)/(2) (6 + 20)5 \\ s = (1)/(2) * 26 * 5 \\ s = 13 * 5 \\ s = 65 \\`

Answer 2

If s = 1/2(v + u)t,

First before replacing the variable let us rephrase the equation.

s = 1/2(v + u)t, can also be written as,

t/2(u + v)

Now replacing the variables,

5/2(6 + 20) = s

2.5 * 26 = s

hence,

s = 65m
