Someone help me with my maths o.o I'll pay u monies in game xD -->
Eve took a photo of her mum on holiday. Later, when Eve looks at the
picture, she sees that her mum seems to be the same height as a hill in
the background.
Eve stood approximately 3 m away from her mum when she took the
photo, and they were approximately 2 km away from the hill. Eve’s
mum is 15 cm taller than Eve.
How tall is the hill?
