Question

Jake walked 10 meters in 5
seconds. What was his speed?
A. 2 m/s
B. 0.5 m/s
C. 50 m/s
D. 15 m/s

Answer 1

To calculate speed, you need to divide distance over time. Which is 10meters/5seconds. Which is 2m/s

Answer 2

Answer:

$\boxed {\boxed {\sf A. \ 2 \ m/s}}$

Explanation:

Speed is the distance traveled per unit of time, or how fast an object is moving.

It is calculated by dividing the distance by the time.

$s= \frac{d}{t}$

Jake traveled 10 meters in 5 seconds.

• d= 10 m
• t= 5 s

Substitute the values into the formula.

$s= \frac{10 \ m}{5 \ s}$

Divide.

$s= 2 \ m/s$

Jake's speed was 2 meters per second and choice A is correct.
