The cyclist traveled at a speed of 20 km / h for the first 3 hours, and in the next 2 hours he covered a distance of 30 km

The cyclist traveled at a speed of 20 km / h for the first 3 hours, and in the next 2 hours he covered a distance of 30 km. What is the average speed of a cyclist along the way?

First, we need to calculate how many kilometers this person traveled on a bicycle when his speed was 20 km / h, because we know that he rode like this for 3 hours:

3 * 20 = 60.

Now we need to find out what total amount of time this person on the bike was in motion:

3 + 2 = 5.

Next, we have to calculate how much distance they have covered for the entire time:

30 + 60 = 90.

Now we can calculate its average speed:

90: 5 = 18.

Answer: It is equal to 18 km / h.
