➜ At 60 mph, the force of your car impacting a surface is ______ times as great as 30 mph.
A.) Two
B.) Four
C.) Six

Four

EXPLANATION: The force of impact in a collision increases exponentially as speed increases. This is the primary factor in why higher speed accidents result in a more fatalities.
