Question

A bald eagle's average speed is about 50 km/h. About how long would it take an eagle to fly 1 kilometer? A. 1 second B. 1 minute C. 1 hour D. 1 day

Answer 1

B. About 1 minute. We can solve this a few different ways and it mostly depends on how you want to go about it. First, we set up the equation as:

distance traveled (x) = time traveled (y)

Since the eagle is going 50 km/hr, we can substitute these variables in.

50 kilometers = 1 hour

Now, neither of these numerical values help us get to the answer, because we want to figure out:

1 kilometer traveled = ?? time traveled.

From the original equation we know to be true, 50 km = 1 hr, we can divide both sides by 50 to convert 50 kilometers to 1 kilometer, and of course, we have to keep the equation balanced, so we divide 1 hr by 50 as well.

50/50 km = 1/50 hr

Solve to:

1 km = 0.02 hr

This is closer to a minute than any other answer when you convert 0.02 hours to minutes (roughly one minute and 12 seconds).
