b.   \(2:46\ \text{pm}\)

Show Worked Solution

a.   \(\text{Match starts at }1:45\ \text{pm}\)

\(\text{Calculate time elapsed until 8 minutes into the third quarter:}\)

\(\text{Total time before intercept}\)

\(=12+3+12+7+8=42\text{ minutes}\)

\(\therefore\ \text{Sarah intercepts the ball at: }1:45+42\ \text{minutes}=2:27\ \text{pm}\)
 

b.   \(\text{Total duration of game}\)

\(=4 \times 12+2 \times 3+7=61\ \text{minutes}\)

\(\therefore\ \text{Finish time}=1:45+61\ \text{minutes}=2:46\ \text{pm}\)
