Question

A train journey is 435 miles. How many centimetres will it be on a map with a scale of 1 cm = 30 miles?

Answer 1

Answer: 14.5 cm

Step-by-step explanation:

You can use dimensional analysis to convert from one unit to another.

435 miles x
`(1 cm)/(30 miles)` = 14.5 cm

The units of miles cancel out and you are left with cm.

The answer is 14.5cm!

Hope this helps! :)
