Answer:
you could go 12 miles paying $7.80 and $1.75
So in total being $9.55
Speed =dist./time
=73.4/5
=14.68 km/hr
I would use miles
Because miles will give you less of an answer
Acceleration = (change in speed) / (time for the change)
Change in speed = (later speed) - (earlier speed) = (13 - 24) = -11 km/hr
Time for the change = 2 seconds
Acceleration = (-11 km/hr) / (2 sec)
Acceleration = -5.5 km/hr-sec (B)
