Two cyclists start at the same place. The first travels East at 22 mile per hour. The second travels west. They are 24 miles apart after 30 minutes. How fast is the second cyclist traveling? Use the equation d=rt.

Answer 1

The second cyclist is traveling at 48 miles per hour.

d = rt
24 = r(30)
r = 24/30
r = 0.8
d = 0.8t
t = 24/0.8
t = 30
d = r(30)
r = 24/30
r = 0.8
d = 0.8t
t = 30
d = 0.8(30)
d = 24
24 = 0.8t
t = 30
r = 24/30
r = 0.8
The second cyclist is traveling at 0.8 x 30 = 24 miles per hour.
