Question

An HOn2- scale train is a model train that is constructed at the ratio 1: 87.1. If an HOn2 model of a locomotive is 10. 4712 inches long, how long is the actual locomotive in feet?

Answer 1

The actual length of the train is 76 ft

Explanation:

Remember that

1 ft=12 in

Convert inches to feet

10.4712 in=10.4712/12=0.8726 ft

we know that

The scale of the train is
`(1)/(87.1)`

That means-----> One unit in the model train represent 87.1 units in the actual train

To find out the length of the actual train, multiply the length of the model train by 87.1

so

0.8726(87.1)=76 ft

therefore

The actual length of the train is 76 ft
