Determine the average speed of the current in a river if a boat moves at 20 miles/hour in still water and takes 3 hours to trave

Taya2010 [7]

The speed of the current in a river is 6 miles per hour

Solution:

Given that,

Speed of boat in still water = 20 miles per hour

Time taken = 3 hours

Distance downstream = 78 miles

To find: Speed of current

If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed downstream = (u + v) km/hr

Speed upstream = (u - v) km/hr

Therefore, speed downstream is given as:

$\text{ speed downstream } = \frac{distance}{time} = \frac{78}{3}\\\\\text{ speed downstream } = 26 \text{ miles per hour }$

We know that,

Speed downstream = (u + v)

26 = 20 + v

v = 26 - 20

v = 6 miles per hour

Thus speed of the current in a river is 6 miles per hour

Which of the following are properties of right triangles?

sineoko [7]

The properties that apply true are:

1–as it implies the Pythagorean theorem; a^2+b^2=c^2

3–as it implies the basic rules of visualized geometry.

4–as the greater side(hypotenuse) is opposite the right angle.

NOT 2, as the accrue angles ARE complimentary.

elaine's mother is now 38 years old. seven years from now she will be five times as old as elaine will be then. write and solve

vfiekz [6]

In seven years her mother will be 38 +7 = 45 years old.

She will be 5 times as old, so divide 45 by 5: 45/5 = 9. Elaine will be 9 years old then, so she is 9-7 = 2 years old now.
