A plane can fly 1440 miles in the same time as it takes a car to go 400 miles. If the car travels 130 mph

patriot [66]

Answer:

The speed will be "144 mph".

Step-by-step explanation:

Let the speed of the plane be "x mph".

then,

The car's speed be "x-130 mph".

According to the question,

⇒ $\frac{1440}{x} =\frac{400}{x-130}$

By applying cross-multiplication, we get

⇒ $1440(x-130)=400x$

⇒ $1440x-187200=400x$

⇒ $1440x-140x=187200$

⇒ $1300x=187200$

⇒ $x=\frac{187200}{1300}$

⇒ $=144 \ mph$
