An airplane took 5 hours to travel 3,420 kilometers. how many kilometers did the plane travel in one hour

684km per hour

Step-by-step explanation:

Time t = 5hrs

Distance d = 3420km

Speed v = distance/time

v = 3420/5

v = 684km/hr

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
