Please help me. there is nothing else 2 say about this question.
Hi Aaron;
distance=(rate)(time)
distance=(12 m/h)(time)
The relationship between distance and time is proportional.
You asked why. This is the reason...
The distance is in miles. The time is in hours.
d miles=(12 miles/hour)(t hours)
Please note that on the right side of the equation, the unit of hours is in the denominator and numerator. It cancels...
d miles=(12 miles/hour)(t hours)
d miles=(12 miles)(t)
The units on both sides are miles. These cancel...
d miles=(12 miles)(t)
d=12t
The reason the two variables are proportional is because of the alignment of the units.
