Selena was comparing the flying speeds of different birds in science class. Which of the three birds flies fastest? Why?
Mashcka [7]

Answer:

Option C. The robin flies fastest because its rate is 15 m/s

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> the distance in meters

The speed is equal to divide the distance by the time

In this problem, the slope or unit rate of the linear equation is the same that the speed

<em>Robin's Flight</em>

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the table

(2,30) and (3,45)

substitute in the formula

m=\frac{45-30}{3-2}

m=\frac{15}{1}

m=15\frac{m}{sec}

<em>Cardinal's Flight</em>

y=10x

m=10\frac{m}{sec}

<em>Blue Jay's Flight</em>

take two points from the graph

(0,0) and (2,20)

substitute in the formula

m=\frac{20-0}{2-0}

m=\frac{20}{2}

m=10\frac{m}{sec}

Compare

The robin flies fastest because its rate is 15 m/s
