Step : 1
Given- acceleration = 16 kilometers/hour2
It means speed increase by 16 kilometers/hour in every 1 hour.
So, In 50 hours, the speed increases by 16x50 = 800 kilometers/hour .
As the intial speed of car is 7 kilometers/hour and the speed increases by 800 kilometers/hour.
So, final speed = (7+800) kilometers/hour
= 807 kilometers/hour.
