Answer:

3 hours 26 minutes

Step-by-step explanation:

1/8 + 1/6 = 1/t  where t is the required time in hours.

Multiply through by 24t:-

3t + 4t = 24

7t = 24

t = 3 3/7 hours

or  3 hours 26 minutes to the nearest minute.

x=3

 y=\sqrt{(3-2)}+5=6

3. The point is (3,6), then it is lie on the graph.

Evgen [1.6K]

Answer:

198 km

Step-by-step explanation:

The speed of the boat supposed to be x km/h

(x+2)*9 = (x-2)*11

9x + 18 = 11x – 22

2x = 40

X = 20

Distance between 2 places: (20 + 2) * 9 = 198 km

Or (20 – 2 ) * 11 = 198 km
