A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
Some examples of rate include cost rates, (for example potatoes cost R16,95 per kg or 16,95 R/kg) and speed (for example, a car travels at 60 km/h). When we calculate rate, we divide by the second value, so we are finding the amount per one unit.

Step-by-step explanation:
3*4/1 = 12/1 =12
Answer:
16 hours
Step-by-step explanation:
velocity = distance / time => distance = velocity * time;
distance = 80 m/s * 12 hours
newVelocity = 60 m/s;
newVelocity = distance / newTime => newTime = distance / newVelocity = 80 m/s * 12 hours / (60 m/s) = (8/6) * 12 hours = 16 hours

Let P = 10x + y
Let Q = 10y + x
Solve
P - Q = 54 Substitute in for x and y
10x + y - 10y - x = 54
9x - 9y = 54 Divide the entire equation by 9
x - y = 6
Start by letting x = 9
9 - y = 6 Subtract 9 from both sides.
-y = 6 - 9
-y = - 3
y = 3
Therefore P is 93 <<<< Answer
Check
93 - 39 = 54 which checks.
