Question: 1 / 400

A motorcycle traveling at 45 mph will cover how many meters during a driver's reaction time of 0.75 seconds?

15 meters

To determine how many meters a motorcycle traveling at 45 mph would cover during a driver's reaction time of 0.75 seconds, we first need to convert the speed from miles per hour (mph) to meters per second (m/s).

1. **Conversion of Speed**:

- 1 mile is approximately 1609.34 meters.

- 1 hour is 3600 seconds.

- Therefore, to convert 45 mph to meters per second, the formula is:

\[

\text{Speed in m/s} = \text{Speed in mph} \times \frac{1609.34 \text{ meters}}{1 \text{ mile}} \times \frac{1 \text{ hour}}{3600 \text{ seconds}}

\]

- Plugging in the numbers:

\[

45 \times \frac{1609.34}{3600} \approx 20.12 \text{ m/s}

\]

2. **Distance Calculated Using Reaction Time**:

- To find out how far the motorcycle travels during the 0.75 seconds of reaction time, we use the equation:

\[
