Answer:
- The rate of planes: 926 km/h and 860 km/h
=========================
<h3>Given</h3>
- Two planes travel in opposite directions,
- One plane travels 66 km/h faster than the other,
- The distance between the two planes after 6 hours is 10716 km.
<h3>To find</h3>
- The rate of of each plane
<h3>Solution</h3>
The distance traveled by two planes in an hour is:
Let the rate of one plane be x, then the other plane's rate is x - 66.
The sum of two rates is the distance traveled in one hour:
- x + x - 66 = 1786
- 2x - 66 = 1786
- 2x = 1786 + 66
- 2x = 1852
- x = 1852/2
- x = 926
So the rate of one plane is 926 km/h and of the other plane is:
