The maximum speed of the Tupolev Tu144 airliner is 694 ms Wh

The maximum speed of the Tupolev Tu-144 airliner is 694 m/s. What is the speed in kilometers per hour?

Solution

If you multiply the top and bottom of 694 m/s by 3600

To convert seconds to hours, you get that: 694 m/s = 2498400 m / 3600 s (or)

694 m/s = 2498400 m/hr

You can divide meters by 1000 to get kilometers. 2498400 m/hr = 2498.4 km/hr
