A kite is flying 40 feet above a stop sign, The child flying the kite is standing 30 feet away from the stop sign. How long is the string from the Child to the kite?

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

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
