Understand the Problem

The question provides a lesson on converting SI and Imperial units, including examples involving foot and kilometers. It asks about the measurement of a Canadian football field in feet and compares distances driven by two individuals, determining who drove further.

Answer

The Canadian football field is approximately $192 \text{ ft}$. Kristen drove farther than Joseph.
Answer for screen readers

The measurement of the Canadian football field is approximately $192 \text{ ft}$.

Kristen drove further than Joseph.

Steps to Solve

  1. Convert the width of the Canadian football field from meters to feet

Given that the Canadian football field is approximately 59 m wide, we will use the conversion factor:

$$ 1 \text{ m} = 3.25 \text{ ft} $$

To convert meters to feet, we multiply:

$$ 59 \text{ m} \times 3.25 \frac{\text{ ft}}{\text{ m}} $$

  1. Calculate the width in feet

Perform the multiplication to get the width in feet:

$$ 59 \times 3.25 = 191.75 \text{ ft} $$

Rounding to the nearest whole number, we get:

$$ \text{Width} \approx 192 \text{ ft} $$

  1. Determine who drove further

Convert the distances driven by both individuals to miles for comparison.

For Kristen driving 114 km:

Using the conversion factor:

$$ 1 \text{ km} = 0.6 \text{ mi} $$

Perform the conversion:

$$ 114 \text{ km} \times 0.6 \frac{\text{ mi}}{\text{ km}} $$

Calculating gives:

$$ 114 \times 0.6 = 68.4 \text{ mi} $$

For Joseph driving 68 mi, no conversion is needed.

  1. Compare the distances

Kristen's distance:

  • Kristen: 68.4 mi
  • Joseph: 68 mi

Since 68.4 mi is greater than 68 mi, this means:

$$ \text{Kristen drove farther than Joseph.} $$

The measurement of the Canadian football field is approximately $192 \text{ ft}$.

Kristen drove further than Joseph.

More Information

This exercise helps illustrate the process of converting between metric and imperial units, which can often come up in various real-life applications, especially in sports and travel contexts.

Tips

  • Forgetting to multiply by the correct conversion factor.
  • Mixing up which unit goes on the top and which goes on the bottom in the conversion fractions. Always check that the units cancel properly.
