The natural history museum has a 1:75 scale model of an apatosaurus dinosaur. the length of the model is 30 centimeters. find the actual length x (in meters) of an apatosaurus.

For this case what we should do is write the expression of the ratios.

We have then:

(75/1) = (x / 30)

Clearing x we have:

x = 30 * (75/1)

x = 2250 cm

Then, you must take into account the following conversion:

1m = 100cm

We have then:

x = 2250 * (1/100) = 22.50m

Answer:

the current length x (in meters) of an apatosaurus is:

x = 22.50m
