Answer:
22.5 hp
Explanation:
The power delivered to an object is given by :
[tex]P=F\times v[/tex]
Where
F is force and v is velocity of the car.
For the same force, power is directly proportional to the velocity.
So,
[tex]\dfrac{P_1}{P_2}=\dfrac{v_1}{v_2}\\\\P_2=\dfrac{P_1v_2}{v_1}\\\\P_2=\dfrac{15\times 30}{20}\\\\P_2=22.5\ hp[/tex]
So, the new power is 22.5 hp.
