Answer:
- boat: 72 km/h
- current: 16 km/h
Step-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

Answer:
24 people in the history class.
Step-by-step explanation:
Let the total number of people in the class = x. I do this rather a long way because people often have trouble dealing with the division of fractions.
Equation
75/100 * x = 18 Multiply by 100
Solution
75x = 18*100
75x = 1800 Divide by 75
x = 1800/75
x = 24
There are 24 people in the class
