Two planes leave the same time. One plane flies 300 kph in west and another flies 450kpk in east. How many hrs will they be 2250 km apart?

It would take 3 hours.
                                              0-0
Hour 1:                       300         -           450
Hour 2:            600                    -                              900
Hour 3:  900                              -                                              1350
1350 + 900 = 2250

Using Linear Equations :)

Let x = be the number of hours the two planes will be 2250 kilometers apart.
300x + 450x = 2250
Simplify
750x = 2250
Divide both sides by 750
750x / 750 = 2250 / 750
x = 3

So they will be 2250km apart in 3 hours.
