In a race of 1300 m, A runs at 10 m/s and B at 9 m/s. What head start should A give B to finish together?
Answer:
130.0
Step-by-step solution: 1. For a dead heat, both runners must take equal time. 2. Use time = distance / speed for each runner. 3. A covers 1300 m while B must cover 1430.0 m at the slower speed. 4. Head start = distance * (1 - speed_B/speed_A) = 130.0 m.

In a race of 1600 m, A runs at 10 m/s and B at 9 m/s. What head start should A give B to finish together?
Answer:
160.0
Step-by-step solution: 1. For a dead heat, both runners must take equal time. 2. Use time = distance / speed for each runner. 3. A covers 1600 m while B must cover 1760.0 m at the slower speed. 4. Head start = distance * (1 - speed_B/speed_A) = 160.0 m.
1563
In a race of 1150 m, A runs at 10 m/s and B at 9 m/s. What head start should A give B to finish together?
Answer:
115.0
Step-by-step solution: 1. For a dead heat, both runners must take equal time. 2. Use time = distance / speed for each runner. 3. A covers 1150 m while B must cover 1265.0 m at the slower speed. 4. Head start = distance * (1 - speed_B/speed_A) = 115.0 m.
1564
In a race of 1250 m, A runs at 11 m/s and B at 10 m/s. What head start should A give B to finish together?
Answer:
113.64
Step-by-step solution: 1. For a dead heat, both runners must take equal time. 2. Use time = distance / speed for each runner. 3. A covers 1250 m while B must cover 1363.64 m at the slower speed. 4. Head start = distance * (1 - speed_B/speed_A) = 113.64 m.
1565
In a race of 550 m, A runs at 8 m/s and B at 7 m/s. What head start should A give B to finish together?
Answer:
