The motorcycle traveled 100 km at a speed of 50 km / h and another 120 km at a speed of 40 km / h. Find the average speed.

First, we need to find out how much the bike was on the road. To do this, we need to find the travel time at each section, and to do this we take and divide the distance by the speed:

100: 50 = 2 hours the motorcycle was traveling at a speed of 50 km / h.

120: 40 = 3 hours the motorcycle was traveling at a speed of 40 km / h.

Now, to find the average speed, we are looking for the total distance traveled:

100 + 120 = 220 kilometers.

Now the total travel time is:

2 + 3 = 5 hours.

Now we divide the total distance by the total time, so we find out the average speed of the motorcycle:

220: 5 = 44 km / h average speed of a motorcyclist.

Answer: 44 km / h.
