A Red-Tailed Hawk leaves its nest and flies 100.0 meters across the sky in 20 seconds, when it spots a garter snake on the ground below. It then flies 50.0 meters in 5.0 seconds to catch the snake. What was the hawk's average speed over his entire journey?

Respuesta :

Answer:

7.5 m/s

Explanation:

A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs

Speed 1= distance/time

= 100/20

= 5m/s

When it spots a garter snake on the ground it flies 50 meters in 5 secs

Average speed= distance /time

= 50/5

= 10 m/s

Therefore the average speed of the hawk over the entire journey can be calculated as follows

= 10+5/2

= 15/2

= 7.5 m/s
