Answer:
Speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
Step-by-step explanation:
Average speed of down stream = 22 km/h
Average speed of up stream = 6 km/hr
Consider the speed of boat in still water be x km/hr and speed of current be y km/hr
As such speed of down stream would be x + y km/hr and speed of down stream would be x - y km/hr. i.e
x+y = 22
x-y = 6
by solving these two equation, we get
2x=28
x=14 km/hr
y=16-13
y=8 km/hr
Hence, the speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
Answer: On a coordinate plane, 2 lines are parallel to each other.
Step-by-step explanation:
The solution of the system of equations of two lines is the intersecting point where both lines intersect.
When two lines intersect at one point then, we say it has a unique solution.
When two lines coincide, then we say it has an infinite number of solutions.
But when two lines are parallel to each other then, we say it has no solution.
Hence, the graph represents a system of equations with no solution:
On a coordinate plane, 2 lines are parallel to each other.
Answer:
58240
Step-by-step explanation:
1425 ------ 45600
1820 ------ x
1425*x = 1425x
45600*1820 = 82992000
1425x = 82992000
82992000/1425 = x
58240 = x
