A car travels 1/6 of the distance between two cities in 3/5 of an hour. At this rate, what fraction of the distance between the two cities can the car travel in 1 hour?
3/5 is 2/5 less than one whole
We need to find how much they traveled in 2/5 of an hour and add that to 1/6
In 1/5 of an hour, they traveled 1/18 of a mile
(1/18)*2=1/9
1/9+1/6=10/36
10/36=5/18
They traveled 5/18 in one hour
As for how I found out 1/18, I was finding 1/5
1/5 goes into 3/5 3 times, so I divided 1/6 by 3
(1/6)/(3/1)
Flip and multiply
(1/6)*(1/3)=1/18
Here's another way of looking at it:
Let the distance betwen the cities be d miles
The speed, s, of the car is distance travelled divided by time taken or (d/6 miles)/(3/5 hours) = (d/6)*(5/3) miles per hour = 5d/18 miles per hour
At this speed the car will travel 5d/18 miles in one hour.
As a fraction of the distance between the cities this is (5d/18)/d or just 5/18
