At what speed does a vehicle travel approximately 31 meters every second?

To determine the speed at which a vehicle travels approximately 31 meters every second, it’s important to convert the distance traveled per second into miles per hour.

First, understand the relationship between meters and miles. One mile is equivalent to approximately 1609.34 meters. To find the speed in miles per hour for a vehicle traveling 31 meters per second, you can use the following conversion:

1. Convert meters per second to miles per hour:

• There are 3600 seconds in an hour.

• Therefore, if a vehicle travels 31 meters in one second, in an hour it would travel (31 \text{ meters/second} \times 3600 \text{ seconds/hour}).

2. This gives:

(31 \times 3600 = 111,600 \text{ meters/hour}).

3. Now convert meters to miles:

• Divide the total meters per hour by the number of meters in a mile:

(\frac{111,600}{1609.34} \approx 69.5 \text{ miles/hour}).

This rounds to approximately 70 miles per hour, which is the correct answer. Recognizing that 70 mph is the closest speed
