Step-by-step explanation:

Given

Worker started from a point 50 from entrance. The worker pushes it away from the entrance at a speed of 1 m/s for 10 s that is there is no acceleration for 10 s as speed is constant.

Distance covered in this time is given by

$\Rightarrow s_1=1\times 10\\\Rightarrow s_1=10\ m$

It is stopped for 5 s and then starts moving towards entrance with a speed of 2 m/s for 20 s. Also, there is no acceleration.

distance traveled in this time

$\Rightarrow s_2=2\times 20\\\Rightarrow s_2=40\ m$

As, distance cannot shown negative. It is shown in increasing manner.
