Brandon and Pat drove from Edmonton to Saskatoon, a distance of 545km. Brandon drove the first part of the trip at an average speed of 100 km/h and Pat drove the remainder at an average speed of 90 km/h. If the trip too Brandon and Pat 5.75 h, determine the number of hours each drove.

B = brandon distance

P = pat distance = 545 - B

 

B/100     +   (545-B) / 90  = 5.75         solve for B   = Brandon's distance ....then   P = 545 - B
