Use the conversion ratio 1 kilometer equals about 0.62 miles to solve the following problem. it may help to set up a proportion. An airplane travels about 900 kilometers per hour. What is the airplane's speed in miles per hour?
To solve this problem, we can set up a proportion using the given conversion ratio:
1 kilometer is equivalent to 0.62 miles.
We can now set up the proportion to find the airplane's speed in miles per hour:
1 kilometer/0.62 miles = 900 kilometers/x miles
Cross-multiplying, we get:
1 kilometer * x miles = 900 kilometers * 0.62 miles
x = (900 km * 0.62 miles) / 1 km
x = 558 miles
Therefore, the airplane's speed is approximately 558 miles per hour.
