Brooke and Ana are going to Chipotle after school. To get there, they travel east on Ives Dairy at 64 km/hr for 15 minutes. Then they turn onto Biscayne Blvd and head south at 56 km/hr for 10 minutes. Assume their starting point was at the origin. What is the coordinate that shows the position of Chipotle?

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
