Remark
The easiest way to do this is to set up a proportion. But be careful how you do it.
Call the distance d
1/2 d / 3/5 hour = x * d / 1 hour
Divide both sides by d
1/2 // 3/5 = x / 1 Cross multiply
1/2 * 1 = 3/5 x divide by 3/5
Invert the bottom fraction and multiply.
The answer is 5/6 of the distance will be covered in 1 hour.
