<span>Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore,
</span>1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)
= (3600/57.1) mi/hours
<span> = 63.047 mi/hours</span>
The living room is rectangular. We would find the area by applying the formula for calculating the area of a rectangle which is expressed as
Area = length x width
From the information given,
internal length = 5.2
internal width = 2.95
Thus,
internal area of the living room = 5.2 x 2.95
internal area of the living room = 15.34 m^2
