7)A car is moving with a uniform speed of 15.0 m/s along a straight path. What is the distance covered by the car in 12.0 minutes?
I don't know
8)What is the resultant of two displacement vectors having the same direction?
The resultant is the sum of the two displacements having the same direction as the original vectors.

7A:
The speed of the car is 15.0 m/s.
The distance the car cover in 12.0 minutes is:
distance = speed * time
distance in meters = 15.0 m/s * 12.0 minutes * ( (60 seconds)/minute))
8:
Your answer is OK.
