I was given this and i need help plz! Question 1: A person has a trip to of 144km to make. How long will the trip take at a speed of 144 km/h? How long will it take a speed of 2km/h? Construct a table showing the time taken (in hours) to complete the journey at 8 different speeds. Draw a graph of speed versus time-with speed on the horizontal axis and the time on the vertical axis. What is the rule connecting speed and time? Question 2: On a hot day a deer is standing in a narrow railroad tunnel, 80 metres from the west end of the tunnel. The deer sees a train approaching the tunnel from the west. the train is travelling at a constant speed - a speed that is 10 times as fast as the deer can run. The deer thinking quickly, realises that if she runs towards the train she will emerge from the tunnel when the train is 20 metres from the tunnel. However if she runs away from the train, she will be hit just as she reaches the end of the tunnel. How long is the tunnel? Question 3: Kym was about to get her maths test results.
