Question

A jet airliner flies at a constant speed, covering 305 miles in 2.9 hours. What is the speed of the plane in miles per hour?

Answer 1

We will have that the speed of the plane is:

$v=\frac{305mi}{2.9h}\Rightarrow v=\frac{3050}{29}mi7h$$\Rightarrow v\approx105.2mi/h$

So, the speed of the jet is approximately 105.2 miles per hour,
