The cyclist rode 2 hours at 11.6 km / h and 4 hours at 10.5 km / h. How many kilometers did the cyclist travel during all this time?

Let’s calculate the distance covered by the cyclist in two hours:

2 * 11.6 = 23.2 km – covered by a cyclist in two hours.

Let’s calculate the distance covered by a cyclist in four hours:

4 * 10.5 = 42 km – covered by a cyclist in four hours.

Let’s calculate how far the cyclist has traveled for the entire time:

23.2 + 42 = 65.2 km – the cyclist has traveled for the entire time.

Answer: 65.2 kilometers.
