In a model of a train, the engine of the train is 9 cm long,while the engine of the actual train is 24 m long. If the length of the engine is 38 m, how long will be the engine in the model train?

Solution

The length of the engines in the model train and actual train will be in direct proportion.

x1 = 9 cm and y1 = 24 m

x2= ?and y2 = 38 m

$\frac{x 1}{y 1}$ = $\frac{x 2}{y 2}$

$\frac{9}{24}$ = $\frac{n}{38}$

n =14.25 cm
