"from zero to sixty in 8 seconds" is a description of:
a) average speed
b) instantaneous speed
d) instantaneous acceleration
I know for sure that a) and c) aren't the right answers since average is over a long time period or the whole trip. I believe b) is the correct answer since speed is a scalar.

It is average acceleration over the eight second period.
