Question 1115839
 Kenneth made a business trip of 260miles. 
He averaged 61mph for
the first part of the trip and 46mph
for the second part. If the trip took 5
5 hours, how long did he travel at each rate?
----
1st part DATA:
rate = 61 mph ; time = x hrs ; distance = 61x miles
2nd part DATA
rate = 46 mph ; time = 5-x hrs ; distance = 46(5-x) miles
-----
Equation:
61x + 46(5-x) = 260 miles
------
61x + 230 - 46x = 260
15x = 30
x = 2 hrs at 61 mph
x-5 = 3 hrs at 46 mph
