Question

The 45-g Wood Thrush migrates every spring from Central America to the United States to breed. The bird leaves its winter
home in Belize and travels 1422 km across the Gulf of Mexico to Louisiana. It then flies an additional 1343 km to reach
Virginia, where it spends the summer. The trip takes approximately 171 hours, flying mostly at night.
What is the average speed of the Wood Thrush?

Answer 1

Answer:

v = 16.16 km/h

Explanation:

Distance covered by Wood Thrush is 1422 km across the Gulf of Mexico to Louisiana + 1343 km to reach  Virginia, where it spends the summer.

d = 1422 km + 1343 km

d = 2765 km

The trip takes approximately 171 hours, flying mostly at night, t = 171 hours

We need to find the average speed of the Wood Thrush. It can be given by :

$v=\dfrac{d}{t}\\\\v=\dfrac{2765\ km}{171\ h}\\\\v=16.16\ km/h$

So, the average speed of the Wood Thrush is 16.16 km/h.
