Exercise 8d
This picture shows the edge of the platform. It
is made of bricks. Can you think why it is painted white?
Inspectors need to know the length of platforms. Can you remember
why? In the last exercise you had to work out the maximum length
of a train.
You could measure a platform by pacing it, but let's imagine that
you have a bad leg.
Each brick is 9cm wide. There are 1100 bricks along the edge of the platform.
Question: How long is the platform in metres?
Answer: | 199m | 99m | 9990m |
