Practice makes perfect
Let's start by copying the given statement.
68mi/h≈mi/secIn this exercise, we need to change miles per hour into miles per second. Since this will involve multiple conversion factors, let's organize them in a table.
Starting Unit
Converted Unit
1 hour
60minutes
1minute
60 seconds
To perform this conversion, we need to multiply the given value by all of these conversion factors. Remember, we need to arrange these ratios such that every unit we do not want gets canceled out and only the units that we want will remain.
