Answer:
30 km/h car
Step-by-step explanation:
From analysis the car traveling at 30 km/h has greater kinetic energy
we can deduce it from the expression of kinetic energy which is

Assuming the mass m= 1 kg
For the 30 km/h

For the 15 km/h

Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE
I hope this is right i think the answer is 40
