Pls help me with these Maths Questions

Postby faith2u » Fri May 29, 2009 11:55 am

Q1). Alan, Bill and Chris had 98 pencils altogether at first. After Alan gave away 5 pencils, Bill doubled his pencils and Chris received 3 more pencils, the ratio of pencils Alan had to the pencils Bill has to the pencil Chris had become 1:4:5. How many pencils did each of them have at first?

Q2). Town S and P are 375km apart. A van started from Town S towards Town P at a uniform speed of 60km/h while a motorcyclist started from Town P to Town S at a uniform speed of 90km/h. Both vehicles started their journey at 0600h.
(a). At what time did they pass each other?
(b). How far away was the van from Town P when it passed the motorcycle?

Thanks in advance.
