Answer:
20 minutes
Step-by-step explanation:
To make one round of the field, Lisa will have to cover the entire perimeter of the field.
The perimeter of a rectangle = 2(l+w) Where L = length and W = width.
The multiplication of 2 means two lengths and widths that each rectangle has. The perimeter of the field = 2(150 +50) = 400m
Lisa's average running speed = 100m/min
The time taken to cover one round of the field or one perimeter of the field = 400/100 = 4 minutes.
To cover 5 rounds or 5 perimeters Lisa will take 5x4 minutes = 20 minutes.
Answer:
Step-by-step explanation:
(-1 + 5)/(4 + 2) = 4/6= 2/3
y + 5 = 2/3(x + 2)
y + 5 = 2/3x + 4/3
y + 15/3 = 2/3x + 4/3
y = 2/3x - 11/3
X(x+2)= 195 that is the correct equation
