The total cost to pay for parking at a state park for the day and rent a paddle boat or shown. (these prices are for both the paddle boats and parking.) number of hours cost1. $172. $293. $414. $53find the cost to park and the hourly rate to rent a paddle boat.

Parking = $5; Boat rental = $12/h

Explanation:

Let’s rewrite your table.

t/h  Cost/$

 1       17

 2      29

 3      41

 4      53

The cost goes up $12 each hour. Parking is constant, so that must be the rate for the boat rental.

If we rent for 1 h, the cost is $17.

If $12 is the cost of boat rental, the difference ($17 - $12 = $5) must be the parking fee.

Parking = $5; Boat rental = $12/h

Check: The same formula works for the other times

2 × 12 + 5 = 24 + 5 = 29

3 × 12 + 5 = 36 + 5 = 41

4 × 12 + 5 = 48 + 5 = 53

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
