Simple. Use this formula:
Time= Distance ÷ Speed,
So if you are driving at 50Km/h, (look at the speedometer) assuming you drive at this speed constantly, time taken will be approx( 5 ÷ 50= 0.1hr=6minutes.)
thus, average speed is what you need to calculate time.

Well, if we think of the basic equation that speed = distance / time.
We are given a distance (5km) and asked to solve for time, so the only missing part of the equation is speed. So your answer is d. average speed.

IS this a homework question or is this a serious query? Firstly, where does your mom live in relation to you? Will you travel by freeway at 90km or through city streets at 50km or by a school zone or playground zone at 30km.
You can likely calculate it most easily be choosing your route wisely and calculating your average speed over that distance.
