Question

To make a model of the Guadeloupe River bed, Hermie used 1 inch of clay for 5 miles of the river's actual length. His model river was 50 inches long. How long is the Guadeloupe River?

Answer 1

it is given that hermie used 1 inch of clay to represent the 5 miles of the rivers actual length.

As the total clay used is 50 inches

so the actual length of the river will be

`\text{total clay used }*\text{river's actual length in 1 inch}`
`50*5=250\text{ miles}`

so the river is 250 miles long.
