How fast did Anjali drive?

Question

Anjali left the hardware store driving east two hours before Ted. Ted drove in the opposite direction going 45 mph slower then Anjali for two hours after which time they were 330 mi. apart. How fast did Anjali drive?

Answer 1

teds speed = x 

anjali's speed = x + 45

 

2x + 4(x + 45) = 330

6x + 180 = 330

6x = 150

x = 25

 

25 +45 = 70

 

70 mph
