Answer:
4 mph
Step-by-step explanation:
The speed downstream is (28 mi)/(2 h) = 14 mph.
The speed upstream is (18 mi)/(3 h) = 6 mph.
The speed of the current is half the difference of these:
(14 mph -6 mph)/2 = 4 mph
_____
The current adds to the downstream speed and subtracts from the upstream speed, so the difference of those speeds is twice the current's speed.

Step-by-step explanation:
10.6 = 10.6 / 1
Numerator = 10.6 × 10 = 106
Denominator = 1 × 10 = 10
Numerator / Denominator = 106 / 10
The simplified fraction:
= 106/10
= 53/5
= 10 3/5
Answer:
B. 0.18
Step-by-step explanation:
