How far could a rabbit run if it ran 36km/h for 5.0min?

Distance = (speed) x (time)

The question GIVES us both the speed and the time.  Sadly, though, in order to work with them, we need them to both have the same units, but the information we're given has two different units for time:  

The speed is in (km per HOUR), but the time is in MINUTES.  We'll have to change one or the other before we can multiply them.

Well, 5.0 minutes is (5/60) = 1/12 of an hour.  We can use that.

Distance = (36 km/hr) x (1/12 hour)

Distance = (36/12) (km-hr/hr)

Distance = 3 km .

= = = = = = = = = =

There's a slightly different way to handle it.  If the problem was more complicated, this way would actually turn out to be a better way, and you'd have LESS chance of making a mistake if you did it this way:

Distance = (36 km/hr) x (5.0 min)

Distance = (36 x 5)  km - min / hr

Distance = 180 km · min / hr

This is a correct answer, but the unit is awkward.  We can change the unit at THIS point in our calculation.  All we have to do is multiply the answer by ' 1 ' !

We'll find a fraction that has the same number on top or bottom, but in different units, and we'll multiply our answer by this fraction.  It won't CHANGE our answer because we're only multiplying it by ' 1 '; but If we're clever about how we build the fraction, it can solve the problem of the units for us.

The fraction to use is . . .  (1 hour / 60 minutes) .

The top and the bottom are the same quantity, so the value of the fraction is ' 1 ', and we can multiply our answer by it without changing the answer. But watch what it does to our units:

Distance = (180 km · min / hr) · (1 hr / 60 min)

Distance = (180 · 1 / 60) (km · min · hr / hr · min)

(Do some canceling, and you get ...)

Distance = 3 km

Thank you.  Thank you very much.  Thank you.  I'll be here until Thursday.  don't forget to tip your waiter.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
