A tortoise traveled 1/6 kilometer in 7/8 hour. What was its average speed in kilometers per hour?

4/21 kilometers per hour

Step-by-step explanation:

Since the tortoise traveled 1/6 kilometers in 7/8 hour we can divide 1/6 by 7 because 7/8 divided by 7 is 1/8 and get 1/42.Once we've done this we can then multiply 1/6 by 8 since 1/8 x 8= 8/8 or 1 hour and get 8/48 which simplifies to 4/21.
