Algebra 1 problems

Please help me with these problems and could you show all the steps?
 
1. A jet leaves the airport traveling at a speed of 560 km/h. Another jet, leaving the same airport and traveling in the same direction, leaves 45 minutes later traveling at 750 km/h. About how long will it take for the second jet to overtake the first jet?
 
2. Bus A leaves Eastport at 7 a.m. at a speed of 40 km/h and is bound for Westport. Bus B leaves Eastport at 7:45 a.m. and drives along the same freeway at 50 km/h. Bus C leaves Westport at 7:45 a.m. traveling towards Eastport along the same freeway at 60 km/h. Westport and Eastport are 220 km apart. Will bus B or bus C pass bus A first?

Your response is accurate and well said, however it may be a bit more beneficial to the student if we,  as tutors,  guide students to get answers on their own rather than just rather solving questions for them.   Have a great Memorial day.

I agree, although I think that the person who writes to this section is looking for an answer of a problem and a methodology of solving it, so he or she will apply the same in other cases. I believe that in five to ten minutes is pretty difficult to cover theoretical basis and also practice the problems, they are at School and the teacher will try to explain the subject. If I am his tutor is another thing. Here I am trying to help them in solving some "difficult" problems.   
Thanks for exposing your point of view and also have a very nice Memorial Day.
