The boat sailed 26% of the distance between the marinas. How many kilometers does he still need

The boat sailed 26% of the distance between the marinas. How many kilometers does he still need to swim if the distance between the marinas is 250 km.

Having calculated 26% of the total distance between the marinas, we will calculate how many kilometers the boat has already covered.

To do this, we need to make a proportion in which the total distance between the marinas is compared with 100%.

250 km – 100%.

x km – 26%.

Let’s do cross multiplication, and divide the result by the number 100.

x = 250 * 26/100.

x = 6500/100.

x = 65 km – the distance that the boat shed.

Next, we calculate the distance that the boat still has to swim:

250 km – 65 km = 185 km.

To summarize: the boat has 185 km left.
