Answer:

3 mph

Step-by-step explanation:

Two cyclists leave town at the same time on the same road going in the same direction.

Cyclist A is going 6 mph faster than cyclist B

Let speed of cyclist B be x mph

Speed of cyclist A be (x+6) mph

Both cyclist leave town at the same time and traveled 8 hours.

Distance covered by cyclist A in 8 hours= 8(x+6)

Distance covered by cyclist B in 8 hours= 8x

After 8 hours cyclist A has traveled 3 times the distance as cyclist B

Therefore, 8(x+6) = 3(8x)

8x + 48 = 24x

24x - 8x = 48

16x = 48

x = 3 mph

Hence, The speed of cyclist B was 3 mph
