1
Q
Avg. Speed
A
Total Distance
Total Time
TD/TT
2
Q
Converging/Divering Scenarios
A
Distance (of object)1 + Distance (of object)2 = Total Distance
D1 + D2 = TD
3
Q
“Catching Up” Scenarios
A
D1 = D2
4
Q
Work Problems (Formulaic Approach)
A
WA + WB = TW
5
Q
Two objects leaving at the same time of day and converging at a constant rate means…
A
Time traveled by both objects is the same
t1= t2
6
Q
Miles/Gallon Rate Question breakdown
A
Rate (miles/gal.) x Gallons = Miles
R x G =M
7
Q
Catch up & Pass Scenarios
SHORTCUT!
A
Change in distance = the total distance to be made up by the object/person catching up.
So…(catch up + pass) = Change in distance
Change in rate = (faster rate) - (slower rate)
