Question

Vocaloid · Answer

to convert Nina's speed from ft/sec to miles per hour:

because there are 5280 feet in one mile, you can divide 63360 ft by 5280 to get to miles

because there are 3600 seconds in one hour, you can divide 3,400 seconds by 3600 to get to hours

then you can divide miles/hour to get Nina's rate in mph. Compare this to Sophia's speed of 10 mph and see which bike is faster.
