Question

A geologist drew a scale drawing of a section of a quartz layer she saw in a cliff. The scale drawing of the layer is 2cm high and 24cm long. If the actual layer is 0.15m high, what is the actual quartz layer section she saw?

Answer 1

1.8 m

Explanation:

the scale drawing of the quartz layer is 2 cm high and 24 cm long.

As sen, the height of layer is 0.15 m

it means, the height 0.15 m is equivalent to 2 cm.

So, 2 cm is equivalent to 0.15 m on scale

1 cm is equivalent to 0.15 / 2 = 0.075 m

On scale length of the quartz layer = 24 cm

Thus, the actual length of the quartz layer = 24 x 0.075 m = 1.8 m
