The cyclist covered 100 km in 7 hours. The first 3 hours, he drove 12 km / h. How many kilometers per hour did he drive in the remaining time?

Let’s find the distance that the cyclist traveled in the first 3 hours, for this we multiply the speed by the time:
12 km / h * 3 hours = 36 kilometers
Let’s calculate how many kilometers he had to drive after that:
100 km – 36 km = 64 kilometers
Let’s calculate the time during which he traveled these 64 kilometers:
7 hours – 3 hours = 4 hours
To find out the speed, let’s divide the distance by the time:
64 kilometers: 4 hours = 16 km / h.
Answer: 16 km / h.
