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 $(r_2)=-45\hat{i}$

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

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