Maybe try 4(2-y)=2y for an equation
Turn 7/10 into decimal. (0.7)
Keep adding by 0.7 until you get the number closest to 4.1
3.5 is the closest, if we add another 0.7, we get 4.2.
So, he can get 5 sections of 0.7m
Answer:
When travelling downstream, the speed of the boat and the current add up.
Let the speed of the boat is b and the speed of the current is c.
<u>Use distance formula: </u>
- d = st, d-distance, s- speed, t- time
a)
<u>Then we have equation:</u>
b)
<u>If c = 2, then the equation is</u>:
- 12(b + 2) = 336
- b + 2 = 28
- b = 26 km/h
