You are on a hike in the mountains. You have 4.76 km left to go before your next campsite.

The sun will set in 5.95 h.

What average speed must you walk to get

to camp at sunset?

Answer in units of km/h.

v = 0.8 km/h

Explanation:

The uniform speed of a body is defined as the ration of the distance traveled by the body to the time taken by the body to cover that distance. Hence, the formula for the calculation of speed will be as follows:

v = s/t

where,

v = speed of the object = ?

s = distance covered by the object = 4.76 km

t = time taken by the object to cover the distance = 5.95 h

Therefore, using the values we get:

v = (4.76 km)/(5.95 h)

v = 0.8 km/h
