If a bus travels 40 km in 30 minutes. What is the average speed of the bus?

the bus is going 27mph

Step-by-step explanation: 40km is 27 miles

1.333333... km per minute

Step-by-step explanation:

To find the average speed devide the speed by the time

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
