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

<em><u>Solution:</u></em>

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

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

Speed downstream = (u + v) km/hr

Speed upstream = (u - v) km/hr

<em><u>Therefore, speed downstream is given as:</u></em>

\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

Michelin Tires would like to estimate the average tire life of its Latitude Tour tire in terms of howmany miles it lasts. Assume
VARVARA [1.3K]

Answer:

6 samples

Step-by-step explanation:

Given :

Sample size, = n

Standard deviation, = 6000

Margin of Error = 2000

Confidence interval, α = 95%

Zcritical at 95% = 1.96

n = (Zcritical * σ) / margin of error

n = (1.96 * 6000) /2000

n = 11760 / 2000

n = 5.88

n = 6 samples
