Irina rode her bike to work at an average speed of 16 miles per hour. It started to rain, so she got a ride home along the same
route in her coworker’s car at an average speed of 27 miles per hour. If Irina’s ride home in the car took 24 minutes (0.4 of an hour), how many hours was her bike ride to work, to the nearest tenth of an hour?
0.7 of an hour this is the correct answer if you put this in your quiz you will get a A for that question if you dont understand ask your teacher but this is the correct answer.
(-6)-9 is the same as -6-9 since parenthesis aren’t really needed in thins case and if you use the order of operations you go left to right. So, -6-9=-15 because a negative- a negative= a negative.
