The running club uses the money they raised to pay for a trip to a canyon. At one point during a run in the canyon, the students are at an elevation of 128 feet. After descending at a rate of 50 feet per minute, they reach an elevation of -472 feet. How long did the descent take?

Respuesta :

Answer:

12 minutes

Step-by-step explanation:

When the students start to descend at a rate of 50 feet/ mins, they were at an elevation of 128 feet.

And at the end of their descend they finally reach an elevation of - 472 feet.

So, the students descend by a depth of [128 - (- 472)] = 600 feet.

As they were descending at a rate of 50 feet/minutes.

Therefore, the descent took a time of [tex]\frac{600}{50} = 12[/tex] minutes. (Answer)
