Distance traveled = speed * time = 45 * 3.2 = 144 miles

speed+=+distace+%2F+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%2Atime+=+%28distance%2Ftime%29%2Atime
speed%2Atime+=+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.

%2845m%2Fh%29%2A%283.2h%29+=+%28144m%2Ah%29%2Fh+=+144+m

Diane drove 144 miles.
