Answer:
The King of the Mountains went up the col at 15 km an hour and down it at 45 km an hour. It took him two hours in total. Assuming that the distance he travelled up and down are the same, how far is it from the bottom to the top of the col?
Step-by-step explanation:
The only technical knowledge we need to know here is the equation
speed = distance/time
On the way up the col, therefore 15 = d/t, where d is the distance up and t is the time it takes to get there.
On the way down, 45 = d/T, where T is the time it takes to get back.
In other words, d = 15t, and d = 45T. Putting these together, 15t = 45T or t = 3T.
