On a map, the length of a nature trail is 7.2 centimeters. If the scale is 1 centimeter to 25 kilometers, what is the actual len
levacccp [35]

Given the scale is 1 cm to 25 km.

We have to find the length of the trail from centimeter to the nearest tenth of kilometer.

Let's take the length of the trail be x km.

The length of the trail given 7.2 cm. We will have to find the length in km.

We have to set it up as a proportion. So we can write the proportion as,

\frac{1}{25} = \frac{7.2}{x}

We have to cross multiply first. We will get,

(1)(x) = (7.2)(25)

x= (7.2)(25)

x = 180

So we have got the required length of the train in kilometer.

The actual length of the trail = 180km.

#8: $900. (I found this answer by multiplying 3000 and 0.3 by the way)
#9: 160 miles. I found this answer by multiplying 80 by two, since two halves/50% make a whole or 100%.
