Problem: A bug runs 4 meters in 8 seconds. Calculate the bug's speed.

Step 1: assign variables.
ΔD = 4 meters
ΔT = 8 seconds
S = ?

Step 2: Formula

The formula you need is:

1.   ?    a = ΔS/ΔT
2.   ?    S = ΔD(ΔT)
3.   ?    S = ΔD/ΔT
4.   ?    S = ΔT/ΔD

Problem: A bug runs 4 meters in 8 seconds. Calculate the bug's speed.

Step 1: assign variables.
ΔD = 4 meters
ΔT = 8 seconds
S = ?

Step 2: Formula
S = ΔD/ΔT

Step 3 is?

1.   ?    Assign variables
2.   ?    Put in numbers
3.   ?    Give the answer
4.   ?    Find the formula

Problem: A bug runs 4 meters in 8 seconds. Calculate the bug's speed.

Step 1: assign variables.
ΔD = 4 meters
ΔT = 8 seconds
S = ?

Step 2: Formula
S = ΔD/ΔT

Step 3: Put in numbers

Which of the following is correct?

1.   ?    S = 4 m/8 sec
2.   ?    S = 8 sec/4 m
3.   ?    4 m = ΔD/8 sec
4.   ?    S = (4 m) X (8 sec)

Problem: A bug runs 4 meters in 8 seconds. Calculate the bug's speed.

Step 1: assign variables.
