You want v2 = v1 + at
v is measured in m/s, a in m/s2, and t in s.
the dimensions multiply like algebraic quantities.
so because v2 is measured in m/s, then (v1 + at) has to come out in m/s
the units for (v1 + at) are (m/s) + (m/s2)(s)
time "s" cancels out one acceleration "s", so it comes ut to (m/s) + (m/s), which = (m/s).
if you had (v1t + a), then you would have (m/s)(s) + (m/s2) which = (m) + (m/s2), which doesn't work.

Answer:
13m & 17m.
Explanation:
Displacement - Shortest distance between the initial and final point. Here ,
=> Displacement = √ ( 12² + 5² )
=> Displacement = √ 144 + 25
=> Displacement = √ 169
=> Displacement = 13 m
Distance - Total path length covered by the body .
=> Distance = 12m + 5m
=> Distance = 17m
