Use the three steps to solve the problem. two planes leave an airport at noon. if the eastbound plane flies at 560 mph and the westbound plane flies at 500 mph, at what time will they be 2,000 miles apart? round your answer to the nearest minute.

The two planes are miles apart at p.m.

Distance miles

When both are traveling in opposite directions, speeds are added.

So, net speed mph.

Time hour minutes.

They leave at noon:

p.m hour minutes p.m

So, the two planes are miles apart at p.m.

The distance formula is:  Distance = Rate x Time.

We know the distance: 2000 miles.

We know the rates: 560 and 500 mph.

We need to solve for time:

2000 = (560 + 500) * T

2000 = 1060 *T

T = 2000 / 1060

T = 1.89 hours ( 1 hour 53 minutes)

They left at noon:

12:00 pm + 1 hour and 53 minutes = 1:53 pm.

step-by-step explanation:

0

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
