Malika wants to calculate the velocity of her mom's car as it travels down the interstate. she knows that her mom is traveling east. what else does she need to know? check all that apply.

she needs to know if her mom was listening to the radio while she drove.

she needs to know how long it took for her mom to get to her destination.

she needs to know how far her mom drove.

She needs to know how long it took for her mom to get to her destination. She needs to know how far her mom drove.Explanation:Velocity is a vector quantity, which means it has both magnitude and direction.It is the ratio of displacement to time taken.

That is; Velocity = Displacement ÷ Time taken

In our case;

Malika needs to determine the velocity of her mom's car.

Apart from knowing the direction the car travels, she also needs to know the time it takes her mom to reach her destination and how far her mom drove.Therefore, if it took her mom time, t seconds to drove for a distance, d meters. Then her mom's car velocity would be;

       Velocity, v = d/t m/s

Where are the questions

D-no effect on the rate
