Question

A hot air balloon was flying at an altitude of 300 meters when the pilot decided to land by descending at a rate of 2 meters per second. For which of these rules does y represent the altitude of the hot air balloon, if x represents the number of seconds since the pilot started her landing?

Answer 1

The answer is "150 seconds".

Explanation:

`\to distance = 300 \ meter\\\\\to speed = 2 \ (m)/(s) \\\\\ formula: \\\\ \bold{speed = (distance)/(time)}\\\\`

`time= (distance)/(speed)\\\\`

`=(300)/(2)\\\\=150 \ seconds`
