You start skiing at an elevation 240 ft from the base of the hill and your elevation decreases 8 ft each minute. your friend starts skiing 320 ft from the base of the hill and her elevation decreases 12 ft per minute. write and solve an equation to determine how many minutes it will take for you to be at the same elevation if you start at the same time.

In this question, it is given that

You start skiing at an elevation 240 ft from the base of the hill and your elevation decreases 8 ft each minute. Your friend starts skiing 320 ft from the base of the hill and her elevation decreases 12 ft per minute.

Let the elevation is represented by h and time by tminutes .

So we have two equations here, which are

And for same elevation, height is same. THat is

THerefore,after 20 minutes, they are at same elevation .

Step-by-step explanation:

Light is considered to be without mass, but it has energy. According to Einstein, energy can be

equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is

so small that it can be ignored and so we say that light travels in a straight line.

The above statement does not hold true when light passes near a star. A star possesses a very

high gravity field that bends light such that the change of direction is observed.
