Lesson 34

Uniform Motion Problems:

D1 + k = D2

Today’s Uniform Motion Problems

• the distance traveled by one object exceeds, by a specified amount, the distance traveled by another object

• Equations will look like: Dist A + 40 = Dist B

• Don’t forget the other two types

Example 34.1• Millicent began the journey at 6 a.m. at 50 kph.

Beauregard began to chase her at 10 a.m. at 60 kph. What time was it when Beauregard got within 40 km of Millicent?

Example 34.2• When the sheriff began his pursuit, Robin Hood was

already 7 miles out of Nottingham. If the sheriff traveled at 6 mph while Robin Hood’s rate was 2 ½ mph, how long did it take the sheriff to catch up?

Example 34.3• Zane began the journey at 5 a.m. at 30 kph.

Tricia began to chase him at 7 a.m. at 40 kph. What time was it when Tricia got within 20 km of Zane?
