To determine which car shows a greater rate of change in distance over time, we can calculate the average velocity of these two cars. The average velocity is given by the formula:

Average Velocity=

Let's calculate the average velocity of A car:

Between (15 min, 2.4 km) and (30 min, 4.8 km):

ΔDistance=4.8 km−2.4 km=2.4 km

ΔTime=30 min−15 min=15 min

Average Velocity=

Between (30 min, 4.8 km) and (45 min, 7.2 km):

ΔDistance=7.2 km−4.8 km=2.4 km

ΔTime=45 min−30 min=15 min

Average Velocity=
