Question

Find each slope from the graph and table to compare the constant speeds of the two airplanes.

Answer 1

Answer:

The constant speed (slope) of Arnie's airplane is: 5

The constant speed (slope) of Bernie's Airplane is: 7

Bernie flew faster. Hope this helps :)

Step-by-step explanation:

Answer 2

Answer:

Constant Speed of Arnie’s airplane = 5 mi/min

Constant Speed of Bernie’s biplane = 7 mi/min

Bernie's Biplane is faster.

Step-by-step explanation:

Arnie' Airplane speed can be determined by calculating the slope.

Also, $\text{Constant Speed} = \frac{\text{Change in distance}}{\text{Change in time}}$

⇒ $\text{Constant Speed} = \frac{\text{10}}{\text{2}}$

⇒ Constant Speed = 5 mi/min

For calculating Bernie's Biplane, The formula used is:

$\text{Constant Speed} = \frac{\text{Total distance}}{\text{Total time taken}}$

⇒  $\text{Constant Speed} = \frac{\text{21 +35+56}}{\text{3+5+8}}$

⇒ $\text{Constant Speed} = \frac{\text{112}}{\text{16}}$

⇒ Constant Speed = 7 mi/min

Hence, Bernie's Biplane is faster.
