Question

The distance above the ground is represented by positive integers and the distance
below the ground by negative integers. In acoal –mine an elevator takes the miners
into the mine at the rate of 10meter per min
b) If it begins to descend from a point 25 metres above the ground level .what will be
it’s position after 25 minutes?

Answer 1

Answer:

(-225) m

Step-by-step explanation:

Distance above the ground is represented by positive integer and distance below the ground is represented by negative integer.

Rate of descent = 10 m/min

If starting point = +25 minutes

Then position of elevator after 25 min = 25 - (10×25) m

= 25 - 250 m

= (-225) m
