    The question is: HELPAAAAAAA A mountain biker moves downhill if he accelerates at 3 m / s2 and takes 15 minutes (900 seconds) down, how far does he travel? HELP ME PLEASE

    Answer: The distance travelled by the mountain biker is 2430 km.

    Explanation:

    Given: Acceleration = 3 m/s^{2}

    Time = 15 minutes (900 sec)

    Displacement = ?

    Formula used to calculate the final velocity is as follows.

    v = u + at

    where,

    v = final velocity

    u = initial velocity = 0 m/s (here)

    t = time

    a = acceleration

    Substitute the values into above formula as follows.

    v = u + a \times t\\v = 0 + 3 m/s^{2} \times 900 s\\= 2700 m/s

    The relation between velocity (speed) and distance is as follows.

    Speed = \frac{Distance}{time}\\2700 m/s = \frac{Distance}{900 s}\\Distance = 2430000 m (1 m = 0.001)\\= 2430 km

    Thus, we can conclude that distance travelled by the mountain biker is 2430 km.
