Question

Question 7 Unsaved Brycen can cover half a basketball court (about 14 meters) in 4.0 seconds flat! How fast can he run? Question 7 options:
3.5 m/s
0.28 m/s
10 m/s
18 m/s

Answer 1

Your answer would actually be A. since the question asks how fast he can run to get across half a basketball court (Which is around 14 meters.) You would multiply 3.5 times 4 to get 14, since m/s stands for Meters per Second, 4 seconds would equate to 14 meters if he was running 3.5 m/s

Answer 2

Use formula $S=v\cdot t,$ where S is a distance, v is a speed and t is a time.

Since Brycen can cover half a basketball court (about 14 meters) in 4.0 seconds flat, then

• S=14 m;
• t=4 s.

Therefore,

$14=4t,\\ \\t=\dfrac{14}{4}=\dfrac{7}{2}=3.5\ m/s.$

Answer: correct choice is A.
