First total number of meters = 11 meters.
First number of seconds = 4 seconds.
Second total number of meters = 13 meters.
Second number of seconds = 12 seconds.
Speed in unit rate =
Plugging values in the formula.
Speed in unit rate =
=
On dividing 2 by 8 , we get 0.25.
Therefore, speed is 0.25 meter per second.
Answer:
B.
Step-by-step explanation:
We are given:
And we want to select its equivalent form.
Note that A is not valid. No integration property allows us to separate factors unless that factor is a constant.
We can simply rewrite and then distribute. First, by rewriting:
Distribute. Recall exponent properties;
Simplify:
This can then be separated (since its addition/subtraction) and integrated individually.
Hence, our answer is B.
