Two planes are 1380 miles apart and traveling toward each other. One plane is traveling
vaieri [72.5K]

Answer: plane 1: 420 mph; plane 2: 500 mph

Step-by-step explanation:

This is a physics exercise, but in order to solve this problem, you need to identify both planes first:

Let's call the plane 1 speed X

V1 = X

And V2 would be:

V2 = V1 + 80 = X + 80

If we combine both speeds:

V = V1 + V2 = X + X + 80 = 2X + 80

Now that we have an expression for the combined speed, let's see the rest of the data:

Distance: d = 1380 mile

Time: t = 1.5 h

We also know that the formula to get speed is:

V = d/t

We have the combined speed, so, let replace it in the above formula to solve for X:

2X + 80 = 1380/1.5

2X + 80 = 920

2X = 920 - 80

2X = 840

X = 840/2

X = V1 = 420 mph

We have V1, so to get V2:

V2 = 420 + 80 = 500 mph

What is 143/13 as a mixed numeral?
yuradex [85]

Answer and Step-by-step explanation:

Hello!

Here~I~will~show~you~how~to~~convert~an~improper~fraction~into~ a~mixed~number!

To~find~the~answer~we~simply~divide~143~by~13.

<u><em>→ We get our answer as:</em></u>

<u><em /></u>\frac{143}{12}=11<u><em /></u>

<u><em /></u>

<u><em /></u>Now,~that~we've~got~11~as~our~answer,~Let's~see~what~a~mixed~number is~so~that~we~can~convert~it.

<em><u>→ What does mixed fraction mean? :</u></em>

<em><u /></em>It~simply~means,~a~mixed~number~has~an~integer~that~is~a~whole integer. So,~to~make~it~into~a~mixed~number~we~need~an~integer~and~ a~fraction~so~we~can~write~it~as:

=11\frac{0}{13}

<u><em>→ And that's your answer!</em></u>
