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?
0.2 of an hour
0.4 of an hour
0.6 of an hour
0.7 of an hour

Best ResponseYou've already chosen the best response.1You can find the distance from the equation \[\large distance=speed \times time\] So plugging in the values for the car ride we get \[\large Distance=27\times0.4\ miles\] Now we need to find the time to travel that distance at 16 mph, which is \[\large t=\frac{27\times0.4}{16}\ hours\]
