10. Lin and Andre biked home from school at a steady pace. Lin biked 1.5 km and it took her 5 minutes. Andre biked 2 km and it took him 8 minutes. a) Draw a graph with two lines that represent the bike rides of Lin and Andre. b) For each line, highlight the point with coordinates (1, k) and find k. c) Who was biking faster?

According to the data, it can be inferred that Lin is faster than Andre because she is going at 0.3 km/min speed while he is going at 0.25 km/min speed.

How to calculate who goes faster?

To calculate who goes faster we must divide the time into the distance traveled by each character as shown below:

  • 1.5km ÷ 5min = 0.3km/min
  • 2km ÷ 8min = 0.25km/min

What is the K point for each character?

According to the above, the point K of each would be equal to the distance that each of them travels in one minute. As shown in the graph, after 5min (Lin) and 8min (Andre), each one reaches their respective destination located 1.5km and 2km away, respectively, taking the point (0,0) as the starting point.

  • Lin: (1,0.3)
  • Andrew: (1,0.25)

The graph is attached.
