Question

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

Answer 1

To reach the campsite before sunset with 3.79 km left to go and 6.93 hours remaining, the average speed needed is 0.547 km/h.

Step-by-step explanation:

To calculate the average speed you must walk to reach your campsite before sunset, you can use the formula: average speed = total distance / total time. Here, the total distance to the campsite is 3.79 km and the time until sunset is 6.93 hours.

So the average speed you need to maintain is:

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

Therefore, to arrive at the campsite by sunset, you must walk at an average pace of 0.547 km/h.

Answer 2

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.
