You are on a hike in the mountains. You have 3.79 km left to go before your next campsite. The sun will set in 6.93 h. What average speed must you walk to get to camp at sunset? Answer in units of km/h

The average speed is equal to the total distance covered in a specific interval of time. Since we are given with the information on distance and time, all we have to do is divide them.

Average speed = 3.79 km/6.93 h = 0.547 km/h

Hence, you should not have a speed less than 0.547 km/h if you want to catch the sunset.
