Question

max is training for a triathlon. he recorded the time for each portion of the race during his practices. max wants to know which event had the most improved time. how did maxs swim time change? max his swim time by ? minutes.

Explanation:

Step1: Calculate the change in swim time

The formula for the amount of change is \( \text{First Practice Time}-\text{Last Practice Time}\).
For swimming, the first practice time is \(60\) minutes and the last practice time is \(48\) minutes.
So the change is \(60 - 48\).

Step2: Perform the subtraction

\(60-48 = 12\)

Since \(48<60\), the time has decreased.

Answer:

Max decreased his swim time by \(12\) minutes.
