A motorboat goes downstream in river and covers a distance between to coastal towns in 5 hours . It covers this distance upstrea

Radda [10]

Answer:

The speed of the boat in still water is 33 km/h

Step-by-step explanation:

Let us denote the speed of the boat in still water as x km/h.

Thus;

Since the speed of the stream is 3 km/h, then while going downstream, the total speed on the boat would be; (x + 3) km/h

Formula for distance = speed x time

Since we are told that the time taken to cover the distance downstream is 5 hours, then;

Distance covered in 5 hours = 5(x + 3) km

Therefore, distance between A and B is 5(x + 3) km

However, while going upstream the boat will work against the water current.

Therefore, its speed upstream will be (x − 3) km/h.

we are told that the time taken to cover the distance downstream is 6 hours, then;

Distance covered in 6 hours = 6(x − 3) km

Therefore, distance between A and B is 6(x - 3) km

The true distance between A and B has to be the same.

So,

5(x + 3) = 6(x - 3)

This gives;

5x + 15 = 6x - 18

15 + 18 = 6x - 5x

x = 33

Therefore, the speed of the boat in still water is 33 km/h

Find the distance between the two points. (1, 2), (7, 6)

zubka84 [21]

$\text {Distance = } \sqrt{(Y_2-Y_1)^2+(X_2-X_1)^2}$

$\text {Distance = } \sqrt{(6-2)^2+(7-1)^2}$

$\text {Distance = } \sqrt{(4)^2+(6)^2}$

$\text {Distance = } \sqrt{52}$

$\text {Distance = } 2\sqrt{13} \ \text { (radical form) or } 7.21 \ \text { (nearest hundredth)}$
