15 Minutes
You have 8 km in an hour.
Divide all that by two and you'll have 4 km in 30 mins.
Then divide by two again to end up with 2 km in 15 mins.
You could alternatively divide by four from the beginning, but I find this easier.

Solved using substitution
For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are
of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
Example:
Answer:
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
