Question

Give brainiest if right!!

Answer 1

Answer:

$4,000\text{ miles}$

Step-by-step explanation:

Let's say that the two planes travel at point $p$. Without loss of generality, let's say that the first plane travels left and the second plane travels right.

Distance is given by $d=rt$, where $r$ is rate or speed and $t$ is time.

If the first plane travels at a speed of 320 mph and the second plane travels 1.5 times this, the second plane must travel $320\cdot 1.5=480$ mph.

Using $d=rt$, the first plane must travel:

$d=320\cdot 5=1600$ miles

The second plane must travel:

$d=480 \cdot 5=2400$ miles

However, these are the planes' respective distances from point $p$. Since they travelled in opposite directions, the total distance between them is equal to $1600+2400=\boxed{4,000\text{ miles}}$

Answer 2

Answer:

4000 miles

Step-by-step explanation:

320x1.5=480

(320x5)+(480x5)=4000

4000 miles
