A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
miskamm [114]

Answer:

We know the distance (d) equation in terms of rate (r) and time (t) as:

d=rt

Step-by-step explanation:

We have given d=336 km and t= 12 hours, so we have: 336 km = 12t <-- this is our equation.

Divide each side by 12 to solve for t:

12t/12=336/12

t= 28 km/ hour

They is 1440 cubic inches and the area of the base is 144 what is the hight
HACTEHA [7]

To find the volume of something, you do the area times the height. In this case you already know the volume so you solve it like this:

(x represents the height since you don't know the value)

1440= 144 * x

1440 = 144x

1440/144= 144x/144

10 = x

Your height is 10:)

why is it not usually realistic to measure the distance between two points on a map as a straight line? explain.
aksik [14]
The map is a flat schematic of some actual distance, on a map, the distance form point A to point B may well be 10 units say, however, in actuality, if you go and walk from point A to point B, you'd notice that, first off is not a straight line most of the time, and also it may have a slanted or sloped section, and the map is not including that slope or hill, whilst you do have to walk it.

so, adding all the twists and curves along the way and any bumps or slopes, is really not exactly 10 units from A to B.
