A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode?
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions. By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then
a = 220 (t) b = 220 (t) + 220 (.25)
And we want to know when these two equal eachother, as that's they will both detonate.
