To change knots per hour, use the expression 1.15k, where k is the speed in in knots per hour. A plane is flying at 300 knots per hour. How fast is that plane flying in miles per hour. Explain step by step.

1.15 (300).

Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.

1.15 (300) = 345 miles per hour

After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).

Since the plane is flying 300 knots per hour.
