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).
