Bob is driving his car behind Alice's car on a highway. The speed of both cars is 80km/h. A moose suddenly appears from the woods and Alice slams her breaks stopping just before hitting the moose. Bob slams his breaks 0.6s behind Alice so that he does not hit Alice's car. Determine how far Bob should have been driving behind Alice in order to not hit Alice's car. Assume that the acceleration of both car's is the same.
Include step-by-step answer and diagram please.
