Surely scalene triangles are covered at GCSE - they're just triangles with 3 unequal sides.

Oh Okay! I don't know how the scalene triangle is connected to this question, is there another way to solve?

A scalene triangle is a triangle where all 3 sides and angles are unequal in magnitude.

What do you know about the area under a line in a velocity-time graph?

Use this to help you work out the distance.

Never got M1 and M2. Guessed a lot of it, got Bs in them. Had to make it up in the pure maths modules to compensate .

area underneath is displacement, but you aren't told the time at -3!!!

You are told the time at the point where it matters. The -3 is telling you the velocity of the truck, is the truck going to deposit its load while going 3m/s? It accelerated to 3m/s then decelerates before it deposits. You are asked for the distance to the point at which is does that.
