Heera jogs 2 rounds of the park, whose length is 4.5 km and width is twice its length .Find the total distance covered by her .

54 km

Step-by-step explanation:

The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle

perimeter of a rectangle = 2 x (length x width)

length = 4.5

width = 2 x 4.5 = 9

2 x (4.5 + 9) = 27km

In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
