Answer:45\hat{i}+50\hat{j}

Explanation:

Truck velocity=50 km/hr

police car velocity =45 km/hr

Let they start at t=0 s

After one hour

truck displacement=50\times 1=50 km

In vector Form(r_1)=50\hat{j}

For Police car displacement=45\times 1=45 km

in vector form(r_2)=-45\hat{i}

r_{12}=50\hat{j}-(-45\hat{i})

r_{12}=45\hat{i}+50\hat{j}
