Answer 1

If you use your subtraction right  when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like 

79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer
