Driving at a constant speed, Reggie travels 300 kilometers in 1 hour. What is Reggie’s speed in kilometers per hour?

Answers

It is given in the question that Driving at a constant speed, Reggie travels 300 kilometers in 1 hour.

So here distance is 300 kilometers and time is 1 hour .

The formula of speed is

speed = (distance)/(time)

Substituting the given values of distance and time, we will get

speed =  \ frac{300}{1} km/hour

So when distance is 300 km and time is 1 hour, so speed is 300 km/hour and that's the answer .

Answer:  300 kilometers per hour

Step-by-step explanation:

Given : Driving at a constant speed, Reggie travels 300 kilometers in 1 hour.

Now, the formula to find speed is given by:-

\text{Speed}=\frac{\text{distance}}{\text{time}}

i.e. Reggie’s speed in kilometers per hour =(300)/(1)

i.e. Reggie’s speed in kilometers per hour =300

Hence,  Reggie’s speed is 300 kilometers per hour.

What is the unit rate for the proportional relationship represented by the equation y=4/5xAnswer choices:
A:4/5
B:-2
C:4
D:5

Answers

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

We have given that,

the unit rate for the proportional relationship is represented by the equation y=4/5x.

We have to determine the unit rate

What is the equation of proportionality?

The equation for proportionality is y = kx, where k is the constant of proportionality.

So in y = 4/5x,

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.
