Maria began riding her bike, from rest, at 6 m/s. If she traveled 500 m, how long was she riding?

she rode for 166.66 seconds , which is about 2 minutes and 47 seconds

Explanation:

We use the kinematic equation that relates initial and final velocities with time and distance travelled that is shown below:

which in our case gives:

which reduced to minutes gives 2 minutes and approximately 47 seconds
