Question 986411: Two cars are moving at constant velocity to the right. Initially (at time t=0) car A is 6.0 miles ahead of car B. Car A has a velocity of 35.4 mph and car B has a velocity of 24.8 mph.
If at some point car B catches up with car A, answer when this will happen (in minutes).
If car B never catches up with car B, answer how far (in miles) the cars are from each other after 10.3 minutes of driving.

Two cars are moving at constant velocity to the right.
Initially (at time t=0) car A is 6.0 miles ahead of car B.
Car A has a velocity of 35.4 mph and car B has a velocity of 24.8 mph.
:
If at some point car B catches up with car A, answer when this will happen (in minutes).
Since Car A (which is ahead of B) is going faster than B, this will never happen
:
If car B never catches up with car B, answer how far (in miles) the cars are from each other after 10.3 minutes of driving.
:
let d = their distance apart after 10.3 min
We are using mph here so change 10.3 min to hrs
10.3/60 = .1717 hrs
d = .1717(35.4-24.8) + 6
d = .1717(10.6) + 6
d = 1.82 + 6
d = 7.82 mi apart after 10.3 min
