Step-by-step explanation:
Let's say b is the rate of the boat in still water, and c is the rate of the current.
Distance = rate × time
Going upstream:
100 = (b − c) (5)
20 = b − c
Going downstream:
100 = (b + c) (2)
50 = b + c
Solve the system of equations using substitution or elimination. Using elimination, add the equations together:
70 = 2b
b = 35
c = 15
The boat's speed is 35 km/h, and the current's speed is 15 km/h.
You divide the shape into as many shapes as you want, and then multiply then all and add!

Answer:
30
Step-by-step explanation:
for every 1 fluid once it is 0.125 cup. So keep adding up and you will get to 240 and the amount will be 30.
