How fast a car would be moving in ft/min if the car’s speed is 74.6 km/h? [1 m = 3.28 ft.].
____________ × 103 ft/min.
74.6 km/hr * 3280ft/km * 1hr/60min = ____ ft/min
This is chemistry? I can see me putting a car in a test tube. Big test tube I guess.

Yes, this is chemistry

To find the speed of the car in feet per minute, we need to convert the speed from kilometers per hour to feet per minute.
First, we need to convert kilometers to meters because the conversion factor given is in meters.
Given:
Speed = 74.6 km/h
Conversion factor: 1 m = 3.28 ft
1) Convert kilometers to meters:
1 km = 1000 m
Using this conversion, we can convert the given speed from km/h to m/min.
74.6 km/h × (1000 m/1 km) × (1 h/60 min) = (74.6 × 1000)/(60) m/min
2) Convert meters to feet:
Using the conversion factor, we can convert the speed from meters per minute to feet per minute.
(74.6 × 1000)/(60) m/min × (3.28 ft/1 m) = (74.6 × 1000 × 3.28)/(60) ft/min
Calculating this expression will give us the speed of the car in feet per minute:
(74.6 × 1000 × 3.28)/(60) ft/min ≈ 4022.67 ft/min
So, the speed of the car would be approximately 4022.67 ft/min.
