Answer:
450
Step-by-step explanation:
Solution for What is 75 percent of 600:
75 percent * 600 =
(75:100)* 600 =
(75* 600):100 =
45000:100 = 450
Now we have: 75 percent of 600 = 450
Question: What is 75 percent of 600?
Percentage solution with steps:
Step 1: Our output value is 600.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$600=100\%$600=100%.
Step 4: Similarly, $x=75\%$x=75%.
Step 5: This results in a pair of simple equations:
$600=100\%(1)$600=100%(1).
$x=75\%(2)$x=75%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
600
x=
100%
75%
Step 7: Again, the reciprocal of both sides gives
x
600=
75
100
Therefore, $75\%$75% of $600$600 is $450$
Answer: the speed of the current is 2.5 mph
Step-by-step explanation:
Let the speed of the boat be x miles per hour
Let the speed of the current be y miles per hour
Speed = distance / time
Time = distance/speed
If the boat goes 12miles downstream(in still water) at 15 mph then, the time is
12/ 15 = 0.8 hours
In still water, it means that it moved in the same direction with the current.
The total speed would be x + y. Therefore
x + y = 15 - - - - - - -1
If the boat goes 8 miles upstream in 0.8 hours, the the speed is
8/ 0.8 = 10 miles per hour
Assuming it moved in the opposite direction to the current.
The total speed would be x -y. Therefore
x - y = 10 - - - - - - -2
Adding equation 1 and equation 2, it becomes
2x = 25
x = 25/2 = 12.5
y = 15 - x
y = 15 - 12.5 = 2.5 miles per hour
