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.

melisa1 [442]

Answer:

9.33 Hours.

Step-by-step explanation:

The time in hours is given by the distance divided by velocity.

t=D/v

Now we are told that the velocity of the ship will be 25054 miles per hour, and the distance to the Moon is 233815 miles; therefore the time it will take the spacecraft to reach the moon will be:

t=233815miles/(25054miles/hr) = 9.33 hours
