Question

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

long was she riding?

Answer 1

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

Step-by-step explanation:

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

`distance=((v_i+v_f)*t)/(2)`

which in our case gives:

`distance=((v_i+v_f)*t)/(2)\\500=((0+6)*t)/(2)\\500=3*t\\t=(500)/(3) \,s\\t\approx 166.66\,sec`

which reduced to minutes gives 2 minutes and approximately 47 seconds
