Answer:
Step-by-step explanation:
- The speed of the boat in the lake = x
- The speed of the current = 3 km/h
<u>Required equation:</u>
- 54 / (x + 3) + 42 / (x - 3) = 96/x
- 9x(x - 3) + 7x(x + 3) = 16(x + 3)(x - 3)
- 9x² - 27x + 7x² + 21x = 16x² - 144
- 6x = 144
- x = 144/6
- x = 24 km/h
Answer:
y=2/1x+5
y=-3/1+3.2
I hope this is what you were asking
The last one- its the only one that applies to the 4* rule.
Answer:
a. 47.6mph (distance divided by time = speed. divide each rowers distance by their speed, then add them all)
b. 1.26 minutes per mile (i used a calculator so i dunno how to explain)
let me know if this is right or not :)
