Chapter 1: Q. 30 (page 30)

Estimate (don’t measure!) the length of a typical car. Give your answer in both feet and meters. Briefly describe how you arrived at this estimate

Short Answer

Expert verified

The length of a car is4.5 meters or 13.5 feets

Step by step solution

01

Write the measurement unit of distance.

  • The quantity like the length, height, or distance is measured in the meters.
  • Meter is the SI unit of distance.
  • The units such as inch, feet, and mile are also used to measure the distance.
02

To estimate the length of a typical car

1 meter = 3 feet (approximately)

  • On average, the length of a car is4.5 meters
  • It can also be expressed in terms of feet
    Since, 1 m = 3 ft, thus;
    4.5 m = 4.5 (3 ft) = 13.5ft
    Therefore, the length of the car is 13.5 feet
