Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
Answer:
4 1/2 cups of flour, 2 1/4 cups of sugar, 1 cup of brown sugar
Step-by-step explanation:
1 1/2 cups flour:3/4 cup of white sugar:1/3brown sugar yields 6 servings. So multiply each amount in the ratio by 3 for 18 servings
It would be: 6(x-6) = 78
6x - 36 = 78
6x = 78 + 36
x = 114/6
x = 19
In short, Your Answer would be 19
Hope this helps!
