Question

Two cars travel next to each other. One speedometer reads

20 meters per second and the other reads 72 kilometers per
hour. If arrows represent speed, which pair of arrows
represents the relationship of speeds of these two cars?
The blue arrow is always the 20 meters per second car.
PLEASE HELP

Answer 1

The pair of arrows which represents the relationship of speeds of the two cars is;

The second option as shown in the attached drawing

Step-by-step explanation:

The given parameters are;

The reading on the speedometer of one car = 20 m/s

The reading on the speedometer of the other car = 72 km/h = 20 m/s

The blue arrow = 20 m/s

Therefore, given that the speeds of both cars are equal (20 m/s = 72 km/h = 20 m/s), the pair of arrows that represent the relationship of speeds of the two cars is two equal length blue arrows which is the second option

The attached diagram showing the pair of arrows that represents the relationship of speeds of the two cars is drawn using Microsoft Visio.
