Question

suppose we represent the distance above the ground by a positive integer that below the ground by a negative integer if an elevator descends at a rate of 5m/ min and begin descends from 15 meter above the ground, what will be it's position after 45 minutes​

Answer 1

Answer:-210m

Step-by-step explanation: distance= speed x time=5 x 45=225m

It is represented by negative sign because it is moving down which is taken as negative.

So,

-225m

So its position = 15 + (-225)=15 -225=-210m
