Question
Ava was traveling in her car at 64 miles per hour (miles/h). Use the fact that 1 km is approximately equal to 0.6214 miles to convert this speed to kilometers per hour (km/h). Round your answer to the nearest tenth. Do not type the units in the space below.
Solution
To convert Ava's speed from miles per hour to kilometers per hour, you need to use the conversion factor that 1 km is approximately equal to 0.6214 miles.
Here are the steps:
- Start with the speed in miles per hour, which is 64 miles/h.
- Since 1 km is approximately equal to 0.6214 miles, you can set up a ratio to find the equivalent speed in kilometers per hour.
- Divide the speed in miles per hour by the conversion factor.
So, the calculation would be:
64 miles/h ÷ 0.6214 = 103.006 km/h
Rounding to the nearest tenth gives you 103.0 km/h.
So, Ava was traveling at a speed of approximately 103.0 kilometers per hour.
