Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s
Given:
The side of a square a, s+3.
The perimeter of a square is the sum of the four sides of the square. Hence,
Answer:
Step-by-step explanation:
Emily wanted to exchange her 300 US Dollars for Canadian Dollars.
The exchange rate for it was 1.25 Canadian Dollars for 1 US Dollar.
This means that 1 US Dollar = 1.25 Canadian Dollars.
So if we were to follow this pattern,
2 US Dollars = 2 × 1.25 = 2.5 Canadian Dollars
3 US Dollars = 3 × 1.25 = 3.75 Canadian Dollars
4 US Dollars = 4 × 1.25 = 5 Canadian Dollars
So for 300 US Dollars, we'll need to multiply 300 by 1.25.
300 US Dollars = 300 × 1.25 = 375 Canadian Dollars.
Hope it helps. :)
