What is the Correct Distance with Force from Both Sides?

Homework Statement

Force of 10N acts on a stationary object of mass 10 kg. after 10 second, a force of 20 N acts on it for 5 s in the opposite direction. what is the distance travelled by the object?

Relevant Equations

f=ma

I am getting distance 87.5m. Is this correct?

The question is ambiguous. Does the first force go away after the 10 seconds or continue? Have you quoted it verbatim?

Either way, I don't get your answer.
Now I do, thanks @Delta2

I suggest you read the forum rules, which specifically state that you have to show your work, not just an answer.

I get 87.5m if i consider that the first force continues to be applied and 75m if it doesnt.

Ahem, yes.
