Answer:
The cost of parking the car for 1 hour = $2.5
Step-by-step explanation:
Cost of parking car for two hours = $5
Now, let the cost of parking the car for one hour be $x
Since, the car is parked for two hours and the cost charged is $5
So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.
Since, the cost of parking the car for one hour = $x
So, cost of parking the car for two hours = 2x
But this cost is given to be $5
⇒ 2x = 5
⇒ x = 2.5
Hence, The cost of parking the car for 1 hour = $2.5
