Two cyclists start at the same place. The first travels east at 24 miles per hour. The second travels west. They are 18 miles apart after 20 minutes. How fast is the second cyclist​ traveling?
Answer provided by our tutors
Let 'v' represent the speed of the second cyclist.
Since distance = speed*time and they are traveling in opposite directions we have:
24*(20/60) + v*(20/60) = 18

v = 30 mph
The second cyclist is traveling with a speed of 30 miles per hour.
