Question

assume that the distance below the ground is denoted by negative integers and above by positive integers. if an elevator starts decending at the rate of 7 m per minute into a coal mine, find the distance of the elevator after 12 minutes.
​

Answer 1

Answer:

-84m

Step-by-step explanation:

• Rate of elevator decending = - 7m/min
• Distance of the elevator after 12 min= - 7×12
• As the elevator is going down/decending
• Therefore, distance of the elevate after 12 min will be= -84m
