• Q3

How is speed related to the distance travelled when a vehicle travels at constant time?

The shorter the distance travelled, the greater the speed of travel.

The greater the distance travelled, the lower the speed of travel.

The speed of travel does not affect the distance covered

The greater the distance travelled, the greater the speed of travel.
