# Runner A begins a \( 100 \)-meter race at time \( t = 0 \) and runs at a constant speed of \( 6.0 \) \( \text{m/s} \). Runner B starts the same race \( 3 \) seconds later but runs at \( 9.0 \) \( \text{m/s} \).

Runner A begins a \( 100 \)-meter race at time \( t = 0 \) and runs at a constant speed of \( 6.0 \) \( \text{m/s} \). Runner B starts the same race \( 3 \) seconds later but runs at \( 9.0 \) \( \text{m/s} \).

**Part a)** Does Runner B catch up before the finish line? *(3 points)*

**Part b)** If so, at what time and distance does this happen? *(3 points)*

**Part c)** Who finishes the race first, and by how much time? *(3 points)*
