Question

Sunita creates a scale model of an aeroplane.
The scale of the model is 5 cm to 9 m.
Sunita's model has a wingspan of 36 cm.
What is the wingspan of the real aeroplane?

Answer 1

Step-by-step explanation:

Scale of the model is = 5:9 or 5/9

Note: model is scaled so wing span would be also in same scale

If scale of wingspan = 36 cm

Orgingal size = 36*9/5 =64.8 cm

64.8 cm is the wingspan of the real aeroplane ✈
