To determine Sally’s walking speed in kilometers per hour (km/h), we can use the formula for speed, which is:
Speed = Distance / Time
In this case, the distance Sally walked is 12 kilometers and the time she took is 14 hours. Plugging these numbers into the formula gives us:
- Speed = 12 km / 14 h
Now, let’s do the division:
- Speed ≈ 0.857 km/h
This means that Sally was walking at an average speed of approximately 0.857 kilometers per hour. To express this in a more understandable way, we can round it:
- Speed ≈ 0.86 km/h
In summary, Sally was walking at an average speed of about 0.86 kilometers per hour. This speed is relatively slow, indicating she may have been taking her time during the walk.
