Question

The table below shows the position of a cyclist. Find the average velocity for each time period.1. [1, 3]Average Velocity:____2. [2,3]Average Velocity:___3. [3, 5]Average Velocity:___4. [3, 4]Average Velocity:___

Answer 1

Hello!

We can calculate the average velocity by using the formula below:

$\frac{s_2-s_1}{t_2-t_1}$

• S, is the distance in meters;

,

• T, is the time.

Knowing it, let's start with the alternatives:

1. [1, 3] Average Velocity: 4.5m/s

$\frac{s_3-s_1}{t_3-t_1}=\frac{10.8-1.1}{3-1}=\frac{9.7}{2}=4.85\text{ m/s}$

2. [2,3] Average Velocity: 5.3m/s

$\frac{s_3-s_2}{t_3-t_2}=\frac{10.8-5.5}{3-2}=\frac{5.3}{1}=5.3\text{ m/s}$

3. [3, 5] Average Velocity: 7.35m/s

$\frac{s_5-s_3}{t_5-t_3}=\frac{25.5-10.8}{5-3}=\frac{14.7}{2}=7.35\text{ m/s}$

4. [3, 4] Average Velocity: 6.7m/s

$\frac{s_4-s_3}{t_4-t_3}=\frac{17.5-10.8}{4-3}=\frac{6.7}{1}=6.7\text{ m/s}$
