## Homework Statement

If a car cruises at 11.3m/s for 75s, then uniformly speeds up until, after 45s, it reaches a speed of 18.5 m/s, what is the car's displacement during this motion?

## Homework Equations

v(1)=at+v(o)

v^2=v(o)^2 +2a(x-xo)

## The Attempt at a Solution

V(o)=11.3

V(1)=18.5

t=45

a=7.2/45=.16

so by plugging in all this values into v^2=v(o)^2 +2a(x-xo) i get 670.5m

But they are telling me the answer is 1.52km
