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.
+37146 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
