Question 922006: It's a simple one, yet I want to fully understand. I want to understand it in a way that I can solve similar questions with time and distance with ease.
If I am driving a car at 15/mph and the distance I have to travel is 3 mi. How long will it take me?

You can put this solution on YOUR website! If I am driving a car at 15/mph and the distance I have to travel is 3 mi. How long will it take me?
-------
time = distance/rate
time = 3 mi/15mph = 1/5 hr = 60/5 min = 12 minutes

You can put this solution on YOUR website!
if you are driving a car at  , means the speed is 
and the distance you have to travel is  , means the distance 
how long will it take you, means what is a time 
as you know, the distance is directly proportional to speed and time:
as speed goes up, travel distance goes up
as time goes up, travel distance goes up
therefore, 
but
speed and travel time are Inversely Proportional because the faster we go the shorter the time
as speed goes up, travel time goes down
and as speed goes down, travel time goes up
therefore, 
so, since you need to calculate the time, use this formula
....plug in given data and
 ...simplify
 ....convert it to min, multiply by 
 => it will take you  to travel the distance of and speed of
