Answer: The speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.
Step-by-step explanation:
Since we have given that
Let the speed of boat in still water be 'x'.
Let the speed of current be 'y'.
Distance = 1 mile
For Upstream, speed would be
For downstream, speed would be
By graphing method we get that
x = 3.558 miles/hr
and y = 1.058 miles/hr
Hence, the speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.

The cash price of the article is 88 cedis.
In this question, the article has a price, but paid in cash, there are two discounts.
- Price of 115 cedis.
- Discount of 15%, thus, 1 - 0.15 = 0.85 is paid, that is, the price is multiplied by 0.85.
- Discount of 10%, thus 1 - 0.1 = 0.9 is paid, that is, the price is also multiplied by 0.9.
Thus, the cash price is:
The cash price of the article is 88 cedis.
