Hiii I think that she wrode her bike 18 miles in one hour because 3 times 5 equals 15 miles and 15 miles equals 50 minutes. So if you add another 3 miles to 15 you get 18 miles in one hour
We want to find the distance that Jana can bike in 60 minutes, we will find that the distance is 18 miles.
We know that Jana can bike 15 miles in 50 minutes, notice that with this information we can find Jana's speed, where speed is the quotient between distance and time.
Speed = (15 miles/50 minutes) = 0.3 mi/min
Now that we know the speed, we can multiply this by 60 min to get:
(0.3 mi/min)*60 min = 18 mi.
This means that in 60 minutes, she bikes a distance of 18 miles.
