90 kph in mph
Understand the Problem
The question is asking for a conversion from kilometers per hour to miles per hour, which involves using a conversion factor between these two units of speed.
Answer
55.92 mph
Answer for screen readers
The final answer is approximately 55.92 mph
Steps to Solve
- Identify the conversion factor
To convert from kilometers per hour to miles per hour, we use the conversion factor $1 ext{ kilometer} ext{ per hour} = 0.621371 ext{ miles} ext{ per hour}$.
- Set up the conversion equation
Multiply the given speed in kilometers per hour (90 kph) by the conversion factor.
$$90 ext{ kph} \times 0.621371 \text{ mph per kph}$$
- Perform the multiplication
Calculate the product of $90$ and $0.621371$.
$$90 \times 0.621371 = 55.92339$$
So, $90$ kph is approximately $55.923$ mph.
The final answer is approximately 55.92 mph
More Information
Speed limits in many countries are given in kilometers per hour instead of miles per hour. Always be cautious of speed limits when driving in different countries due to these differences.
Tips
A common mistake is to forget to multiply by the conversion factor or to use the wrong conversion factor. Make sure to use the correct conversion factor of 1 kilometer per hour = 0.621371 miles per hour.
