Same d = rt
so the boat's still water speed is 20kph, if we... say the current of the river is "r", then, when the boat was going upstream, its speed was " 20 - r", and when it was going downstream, is " 20 + r", since the river's current is adding speed to it
again, if on the way up, it took "t" hours, on the way down, it took the slack of the 3hrs, or " 3 - t"
thus
solve for "r"
I=PRT
1000*.008=80
80*6=480

Answer:
Mean of the data set is one of the most commonly used measures of central tendency. Basically, it means the average value of the data set. For finding it, one doesn't have to arrange the data in order. All it takes is to add them all together and divide that by the number of the data. It can be mathematically written as:
(x1 + x2 + x3 + ..... + xn) / n
This obviously means that Ashrita did the best job in calculating the mean of this data set.

Answer:
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
