A body starts from rest and moves with a uniform acceleration of `10ms^(-2)` for 5 seconds. During the next 10 seconds it moves with uniform velocity. Find the total distance travelled by the body (Using graphical analysis).

Explanation

To solve the problem step by step, we will analyze the motion of the body in two phases: the first phase with uniform acceleration and the second phase with uniform velocity.

### Step 1: Calculate the final velocity after the first phase
The body starts from rest, which means its initial velocity \( u = 0 \, \text{m/s} \). It accelerates uniformly at \( a = 10 \, \text{m/s}^2 \) for a time \( t = 5 \, \text{s} \).

Using the first equation of motion:
\[
v = u + at
