Use a conversion ratio 1 km equals about 0.62 miles to solve the following problem and airplane travels about 900 km/h. What is the airplane speed limit per hour?

To find the speed limit in miles per hour, we need to convert the speed from kilometers per hour to miles per hour using the conversion ratio.

First, we can set up the conversion ratio:

1 km = 0.62 miles

Next, we can multiply both sides of the conversion ratio by the airplane's speed:

(1 km/0.62 miles) * (900 km/h) = 900/0.62 miles/h

Simplifying the expression on the right side:

900/0.62 ≈ 1451.61 miles/h

Therefore, the airplane speed limit per hour is approximately 1451.61 miles/h.
