This is the problem word for word: A student throws a baseball at a large gong 48 m away and hears the sound of the gong 1.18893 s later. The speed of sound in air is 330 m/s. What was the average speed of the baseball on its way to the gong? (For simplicity, assume its trajectory to be a straight line.) Answer in units of m/s. I don't need the answer. I'd really just like to be pointed in the right direction. Thanks so much.
