The velocity of a train grows uniformly from $0$ to $30 m / s$ in $10$ s, stays $30 m / s$ for the next $10$ s and then falls uniformly to $0$ in $12$ s. The total distance travelled is:

Options:

Answer:

Solution:

Areas: $\frac{1}{2} (10) (30) = 150$ m, $(10) (30) = 300$ m, $\frac{1}{2} (12) (30) = 180$ m; total = $150 + 300 + 180 = 630$ m. Option B.
