Question \#12 Franklin wants to know how fast he runs different distances. He uses a stopwatch to measure the time it takes him to complete a 50 -meter, 100 -meter, and 200 -meter race. How can he calculate his speed for each race?

To calculate his speed for each race, Franklin can use the formula for speed, which is: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \] Here's how he can apply this formula for each race: 1. **50-meter race**: - Measure the time it takes to complete the 50 meters (let's say it takes \( t_1 \) seconds). - Calculate the speed using the formula: \[ \text{Speed}_{50} = \frac{50 \text{ meters}}{t_1 \text{ seconds}} \] 2. **100-meter race**: - Measure the time it takes to complete the 100 meters (let's say it takes \( t_2 \) seconds). - Calculate the speed: \[ \text{Speed}_{100} = \frac{100 \text{ meters}}{t_2 \text{ seconds}} \] 3. **200-meter race**: - Measure the time it takes to complete the 200 meters (let's say it takes \( t_3 \) seconds). - Calculate the speed: \[ \text{Speed}_{200} = \frac{200 \text{ meters}}{t_3 \text{ seconds}} \] After calculating the speeds for each distance, Franklin will have his running speeds for the 50-meter, 100-meter, and 200-meter races.
