Question. 51
t minutes are equal to 60t seconds.
Answer:
true
Detailed Answer with Explanation:
Idea: The letter t stands for any number of minutes.
Known fact:
\(1\ \text{minute} = 60\ \text{seconds}\)
Step 1: Multiply both sides by \(t\).
\(t \times 1\ \text{minute} = t \times 60\ \text{seconds}\)
Step 2: Simplify each side.
\(t\ \text{minutes} = 60t\ \text{seconds}\)
Conclusion: The statement is true because \(t\) minutes equals \(60t\) seconds.
Quick check (example):
If \(t = 3\), then \(3\ \text{minutes} = 60 \times 3 = 180\ \text{seconds}\), which is correct.
