PLEASE HELP SOON! Please answer the question and explain step by step how you got your answer. Julian is using a biking app that

compares his position to a simulated biker traveling Julian's target speed. When Julian is behind the simulated biker, he has a negative position. Julian sets the simulated biker to a speed of 20 km/h. After he rides his bike for 15 minutes, Julian's app reports a position of -2 1/4 km.
What has Julian's average speed been so far?

Answer:

<u>11 km/h</u>

Step-by-step explanation:

What I did is found out how fast the simulated biker traveled for 15 minutes, by doing

\frac{20}{4} = 5

Since 15 minutes is 1/4 of an hour. Or you could do 20/60 = 1/3,  1/3 being  how much the biker traveled in a minute and multiply that by 15

15×\frac{1}{3} = 5

Now we know that the biker traveled 5 km, now subtract 5 by 2 \frac {1}{4}

5 - 2 \frac {1}{4} =    2 \frac {3}{4}

Julian traveled  2 \frac {3}{4} in 15 minutes, now to find his average speed you multiply 2 \frac {3}{4} by 4 since 2 \frac {3}{4} is the distance traveled in 1/4 an hour.

2 \frac {3}{4} × 4 = 11

11 km/h
