Answer:
1.07 m/s
Explanation:
This is a simple speed distance time question.
first, we need to determine the distance between -11 and 4.
(think of a number line).
We add 4 to 11 using absolute value (i.e taking away negatives), and we get 15 m, our distance. We are attempting to find speed, and we have our time.
Speed is distance/time.
Now we have our equation, we plug in our variables.
speed (aka velocity)= 15/14.
speed= 1.07142857143
If we round to 2 place values, our speed is 1.07 m/s.
