Answer 2

Ответ:

1) 27,2 * 1.8 = 48,96

2)48.96 - 45,9 = 3.06

Ответ : 3.06

Answer 3

To find the speed of the river's current, we can use the formula:

Speed of the boat (against the current) = Speed of the boat in still water - Speed of the current

Given data: Distance traveled by the boat against the current (d) = 45.9 km Time taken (t) = 1.8 hours Speed of the boat in still water (b) = 27.2 km/h

Let's use the formula to find the speed of the current (c):

Speed of the boat against the current = Distance / Time 27.2 km/h - Speed of the current = 45.9 km / 1.8 h 27.2 km/h - Speed of the current = 25.5 km/h

Now, let's isolate the speed of the current:

Speed of the current = 27.2 km/h - 25.5 km/h Speed of the current = 1.7 km/h

So, the speed of the river's current is 1.7 km/h.
