How do I convert 75 feet/second to miles/hour rounding to the nearest whole number
MAVERICK [17]

Answer:

51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

Step-by-step explanation:

Given:

75 feet/second.

Now, to convert 75 feet/second into miles/hour.

So, to convert we divide the value of feet per second by conversion factor to get miles per hour.

Value of feet per second = 75.

Conversion factor = 1.4667.

Now, putting the formula to get the value in miles/hour:

Value in miles/hour = value of feet/second ÷ conversion factor.

Value in miles/hour = 75\div 1.4667.

                                 = 51.135\ miles/hour.

<em>Rounding nearest to whole number = 51 miles/hour.</em>

Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
