Question

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

Answer 1

Please help!

Answer 2

In the car it's 27miles per hour and it takes .4so to determine the distance travelled you do 27x0.4

Answer 3

Once you figure out the distance you can then use the distance divided by her travel speed so 16 to find the time it takes her to get to work
