Answer:
58/45
Step-by-step explanation:
4/9 + 4/9 + 2/5
8/9 + 2/5
- 8/9 ⋅ 5/5 = 40/45
- 2/5 ⋅ 9/9 = 18/45
40/45 + 18/45 = 58/45
Answer:
8 mph
Step-by-step explanation:
The speed in each direction is the speed of the boat with the speed of the current appropriately added. If x is the speed of the current, the upstream speed is 13-x; the downstream speed is 13+x.
The ratio of times is inversely proportional to the ratio of speeds, so we ahve ...
15/63 = 5/21 = (13-x)/(13+x)
5(13 +x) = 21(13 -x) . . . . . . . cross multiply
26x = 13(21 -5) = 13·16
x = 13·16/26 = 16/2 = 8
The speed of the current is 8 miles per hour.
