But the velocity has increased to an extent and so acceleration should have increased before becoming constant. Shouldn't that still be the acceleration at 40s.

Firstly as V=CONST then a = 0;
Now for 's' we know that area under v & T gives distance change.
So, that (10 * 80)/2 + 30 * 80 = 2.8 km.
Now for 's' we know that area under v & T gives distance change.
So, that (10 * 80)/2 + 30 * 80 = 2.8 km.

What you do is you have to control your hand first without typing?

a= 0
because const speed
