Riverside Walk is a popular walking path, 3.2 kilometres long, beside the River Bee. There is a seat situated at each end of the path and also every 400 metres in between. There are two litter bins just next to every seat and one litter bin every 100 metres between each seat and the next.

1. How many litter bins are there along Riverside Walk?
  • 1
    0

    Explanation

    The correct answer is B.

    Start by calculating the number of benches – that’s 2 at each end and one every 400m of a 3200m path or 9 seats total. This accounts for 18 bins overall next to the benches. Now, remember that for 9 seats there will be 8 gaps. With a bin every 100m, there will be 3 bins between every 2 seats for a total of 8 x 3 = 24 bins. Adding up, we have 24 + 18 = 42 bins overall.

     

    Top tip!

    Convert your values to the same units before starting! 3.2km=3200m which makes calculations in your head easier.
