80 km / h = 22.23m/s
60 km /h = 16.67 m/s
acc. = 16.67-22.23/ 5
= -5.56 / 5 = -1.11 m/s^2
60 km /h = 16.67 m/s
acc. = 16.67-22.23/ 5
= -5.56 / 5 = -1.11 m/s^2

Doing this again with a calculator would make you understand this way more clear
Velocity is converted from kmph to m/s since the time is given in seconds
