Answer 1

To convert 70 miles per hour (mph) to meters per second (m/s), we can follow these steps:

1. **Convert miles to meters:**
We know from your data that:
- 1 mile = 5,280 feet
- 1 foot = 12 inches
- 1 inch = 2.54 cm
- 1 meter = 100 cm

So, we first convert miles to feet:
\[
70 \text{ mph} = 70 \text{ miles/hour} \times 5,280 \text{ feet/mile} = 369,600 \text{ feet/hour}
\]

Then, convert feet to inches:
\[
369,600 \text{ feet/hour} \times 12 \text{ inches/foot} = 4,435,200 \text{ inches/hour}
\]

Now convert inches to centimeters:
\[
4,435,200 \text{ inches/hour} \times 2.54 \text{ cm/inch} = 11,296,128 \text{ cm/hour}
\]

Finally, convert centimeters to meters:
\[
11,296,128 \text{ cm/hour} \div 100 \text{ cm/m} = 112,961.28 \text{ m/hour}
\]

2. **Convert hours to seconds**:
There are 3,600 seconds in an hour (60 seconds/minute × 60 minutes/hour):
\[
112,961.28 \text{ m/hour} \div 3,600 \text{ seconds/hour} = 31.362 \text{ m/s}
\]

Thus, the conversion of 70 mph to meters per second is approximately **31.362 m/s**.
