Answer 1

Answer:

1.) 0.075 km/min

2.) 0 km/min

3.) -0.15 km/min

Explanation:

Formula:

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

• s = speed
• d = distance
• t = time

Calculating the speed:

1.) $\frac{1.5-0}{20-0}=\frac{1.5}{20}=0.075$

2.) $\frac{1.5-1.5}{40-20}=\frac{0}{20}=0$

3.) $\frac{0-1.5}{50-40}=\frac{-1.5}{10}=-0.15$
