Question 859413
{{{speed = distace / time}}}, right?


And you want to know the distance. So you rearrange this formula in terms of distance.


Cancel out "time" from the right fraction by multiplying the equation with it.
{{{speed*time = (distance/time)*time}}}
{{{speed*time = distance}}}


Now you plug in the numbers, and units for speed and time and work out distance. Speed and time must have the corresponding units, and here they do - miles per hour and hour.


{{{(45m/h)*(3.2h) = (144m*h)/h = 144 m}}}
