Barbara saw her favorite band, Royal Gems, perform on Friday night. She paid $77.50 for a ticket to the show. She also had to pay for the 4 hours her car was parked in the parking garage. Barbara spent a total of $89.50. Which equation can you use to find x, how much it cost for each hour Barbara's car was parked in the garage?

Answer:

cost for each hour her car was parked in garage =  $3

Step-by-step explanation:

Let the cost every hour car parked in garage be x.

4x + $77.50 =  $89.50 4* x because the car had been 4 hours in garage.

4x = $89.50 - $77.50

4x = $12

x =  $12 / 4

x =  $3

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
