🚗 Chemistry by Chang – Problem 1.34 | Unit Conversion: Speed | Steemit Science

in Popular STEM2 months ago

Hello Steemit science fans! 👋⚗️

Here’s another engaging problem from Raymond Chang’s Chemistry (14th Edition), in Chapter 1: Measurement and the Properties of Matter.
It focuses on converting units of speed, an everyday application of dimensional analysis that’s also essential in scientific calculations.


🔹 Problem 1.34:

The speed limit on parts of the German autobahn was once set at 286 kilometers per hour (km/h).
Calculate the speed limit in miles per hour (mph).


This problem applies a straightforward unit conversion between metric and imperial systems.
Knowing that:
1 mile = 1.609 km
we can easily convert between both systems using a simple proportional relationship.

This kind of conversion is particularly useful for travelers, engineers, and scientists working with international data.
