Question

John drained the water in his tub. The amount of water left in the tub (in liters) as a function of time (in minutes) is graphed.

How much water is getting drained in five minutes?

  1. 360
  2. 260
  3. 140
  4. 0

hintHint:

John drained the water in his tub. In that given graph we can look x-axis as a time and y-axis as a water. We need to focus on graph whether that is given that the amount of water remove as per time and by that we are able find the solution easily.

The correct answer is: 360


    Here we need to find the amount of water remove in 5 minutes.
    Firstly, in a graph x-axis which is also horizontal axis is the time of graph.
    And , y-axis is which is vertical axis is the Amount of water at a time t minutes.
    graph
    If we look on x-axis which time the given time is 5 minutes.
    And on the other hand when we look on the y-axis which is water(liters) in given time,
    The amount of water remove in 5 minutes is 360 liters.
    So, the Answer is 360 liters or 360 (option (a)) .

    In that same question we can also fine the how much amount of water remove in one minutes by 360/5=72. Which leads to us to find the water drained at any given minutes by multiplying in it.

    How many increasing/decreasing intervals are there in this graph?

    It very easy to find the increasing and decreasing interval in graph you just have to focus on the graph where its going upward or downward or you can also find increasing and decreasing by finding the slope of the line. If the slope is positive then line is increasing otherwise slope is negative then line is decreasing.
