Question

An airplane can level 1,500 miles in 4.5 hours at a constant speed how long will it take the airplane to travel 200 miles

Answer 1

Answer: 0.6 hours

Explanation:

We will set up a proportion to help us solve.

`\displaystyle (1,500\; \;miles)/(4.5\;\;hours) =(200\;\;miles)/(x\;\;hours)`

Next, we will cross-multiply and solve by multiplying and using inverse operations.

1,500 * x = 200 * 4.5

1,500x = 900

x = 0.6 hours
