a boat traveled from pier a to pier b with the current in 2 hours. how far from each other are these piers, if the return trip took 6 hours, and the current speed is 2.5 mph?

The distance from Pier A to Pier B can be determine by using speed formula.

The distance from Pier A to Pier B is .

Given:

The time to reach from Pier A to Pier B is 2 hour.

The time took in return is .

The speed is .

Write the speed formula.

Where, is velocity, is time and is distance.

When boat go pier A to B with the current of 2.5 mph.

Calculate distance return time.

The above equation we can write as,

Now, the substitute the value of .

Thus, the distance from Pier A to Pier B is .

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
