You'll find the answer at the bottom, To find the speed of the Formula 1 car in feet per second (ft/sec), we can use the conversion factors provided:
225 mi
-------
1 hr
5280 ft
--------
1 mi
1 hr
-----
60 min
1 min
-----
60 sec
To set up the conversion, we need to cancel out the units we don't need and keep the units we want (ft/sec).
The correct set up to find the speed of the car in ft/sec is:
225 mi 5280 ft 1 hr 1 min 1 sec
------- × -------- × ------- × ------- × ------- = X ft/sec
1 hr 1 mi 60 min 60 sec 1 min
By multiplying the given value of 225 mi/h with the conversion factors, we can find the speed of the car in ft/sec.
To solve for X, we can cancel out the units and perform the necessary calculations:
225 mi 5280 ft 1
------- × -------- × ------- × ------- × -------
1 hr 1 mi 60 min 60 sec
= (225 × 5280 × 1) / (1 × 1 × 60 × 60) ft/sec
= 7920 ft/sec
Therefore, the speed of the Formula 1 car is 7920 ft/sec.
