Answer 1

Question: If a car is moving on a road at 70 km/hr going due north, and then changes direction and starts traveling north-east staying at 70 km/hr, what happens to its speed and velocity?

Answer: the velocity of the car changes, but the speed stays the same.

Explanation: basically velocity is speed with a direction and speed is the absolute value or magnitude of velocity.

Answer 2

Velocity of the car changes while the speed will remain the same

Step-by-step explanation:

As we know that the speed is the magnitude of rate of change in the position of the object

So here we have

`speed = (distance)/(time)`

while for finding velocity we know that it is rate of change in the position along with the direction of the motion

So it is given as

`velocity = (displacement)/(time)`

so here we can say that magnitude of the velocity in both is same while the direction is different

so correct answer will be

Velocity of the car changes while the speed will remain the same
