The diagram below shows the distance-time graph of an object \(A\) from point \(P\) during a one-minute interval.

  1. Find the average speed of the object during the \(1\) minute interval.
  2. A second object \(B\) travels at a constant speed of \(5\) m/s, starting at point \(P\). On the same axes above, draw the travel graph for this journey. Use your graph to answer the following questions:
    1. After how long does object \(A\) meet object \(B\)?
    2. How long does it take object \(B\) to cover the same total distance as object \(A\)?
