In a rally race the lead car is ahead by 1 1⁄2 hours. if the lead car is going 60 mph and the second place car is going 70 mph and starts 1 1⁄2 hours after the lead car, how long will it take to overtake the leader?

Let t hours be the time the second car is driving untill it overtakes the first car. The nfirst car is hours on the road.

If the lead car is going 60 mph, then for the hours  it will go the distance

If the second place car is going 70 mph, then for the hours it will go the distance

These distances are equal, then

9 hours

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
