I think is A but Im not 100% sure.

Answer 3

first you need to calculate the amount of distance and time passed between 2.8km and 4.2km.
You would start by subtracting 4.2 - 2.8 and get 1.4km passed
Now we are going to see how much time passed 0.084 - 0.051 and get 0.033 seconds
Finally we are going to divide distance by time \[\frac{ 1.4 }{ 0.033 }\] = 42 km per hour or 42 km/h
