A mountain climber is currently 77 feet above ground level on the side of a cliff. She is climbing at the rate of about 7
horrorfan [7]

The climber would be at a height of 224 meter.

<h3>How to calculate elevation ?</h3>

Elevation is simple to calculate. You must first determine the unit rate, which is determined by dividing the height by the passage of time, before merely multiplying it by the passage of time.

Given, the climber is currently at a heigh of 77 feet.

And she is climbing at the rate of 7 feet per min

thus as we know that unit rate= elevation÷ time

Given unit rate is 7 feet min-1

So 7= 77/time

On calculating further we get,

time = 11 minutes

Thus the climber can cover 77 feet in 11 min

So distance covered by the climber in 1 min is 77/11 = 7 feet

Therefore after 32 minutes the climber will cover 32×7= 224 feet.
