Calculating Distances In A Storm

Classical Mechanics Level 2

Tim's father has a very large farm that spans several kilometers. During a heavy thunderstorm, he is worried that lightning could have destroyed his barn that is located 1,700 meters from the house. He constantly stares out the window, and feels completely helpless.

If lightning did indeed strike the barn, how long (in seconds) does it take between Tim seeing the lightning strike and hearing the sound of thunder?

Note: Light travels at 300,000,000 m/s, and sound travels at 340 m/s.
