(from unit 5, lesson 12.)

Explanation:

Step1: Convert minutes to hours

We know 1 hour = 60 minutes. To convert 240 minutes to hours, calculate $\frac{240}{60}$.
$\frac{240}{60}=4$

Step2: Convert minutes+seconds to seconds

We know 1 minute = 60 seconds. First convert 2 minutes to seconds: $2\times60=120$, then add 45 seconds.
$2\times60 + 45=120+45=165$

Step3: Convert hours to minutes

We know 1 hour = 60 minutes. Multiply 112 hours by 60.
$112\times60=6720$

Step4: Convert seconds to minutes

We know 1 minute = 60 seconds. Divide 540 seconds by 60.
$\frac{540}{60}=9$

Answer:

a. 4
b. 165
c. 6720
d. 9 minutes
