<PRE><B>Question 544801</B>
how long will it take danette to travel 90 miles if she drives at an 
average speed of 50 mph for 25 miles and at an average speed of 
65 mph the rest of the way?
----------------------------------
time = 25/50 + (90-25)/65
---
time = (1/2) + 65/65
---
time = 1.5 hours
