Suzie the slug is travelling at a speed of 0.45 millimeters per hour. Calculate her speed in
meters per second and feet per minute. You must show your work and you may only use
the following conversion factors: 1 hr = 60 min, 1 min = 60 sec, 1000 mm = 1 m, 100 cm
= 1 m, 1000 m = 1 km, 2.54 cm = 1 inch, 12 inches = 1 ft.
The answer I got is: 0.45mm/hr * 1in/2.54cm * 1hr/3600s = 1.25*10^-7m/sec
0.45mm/hr * 1in/2.54cm * 1ft/12in * 1hr/60min= 2.54*10^-4ft/min
I asked 4 different people for help, and I received four different answers and I want to be sure. Thanks
awful slow !!
0.45 mm/hr (1 m/ 1000 mm) (1 hr/60 min)(1 min /60 s)
mm cancels
hr cancels
min cancels
meters/seconds is left
0.000000125 = 1.25 * 10^-7 m/s
as you said
1.25 * 10^-7 m/s (100 cm/1 m)(2.54 in/cm)(1 ft/12 in)(60 s/min)
= 0.000159 ft/min
To calculate Suzie the slug's speed in meters per second, we'll use the given conversion factors:
1 hr = 60 min
1 min = 60 sec
1000 mm = 1 m
We start with the given speed of 0.45 millimeters per hour and convert it to meters per second.
Step 1: Convert hours to seconds
0.45 mm/hr * 1 hr/3600 s = 1.25 * 10^-7 m/s
Therefore, Suzie the slug is traveling at a speed of 1.25 * 10^-7 meters per second.
To calculate her speed in feet per minute, we'll use the given conversion factors:
2.54 cm = 1 inch
12 inches = 1 ft
1 min = 60 sec
Step 1: Convert millimeters per hour to feet per minute
0.45 mm/hr * 1 in/2.54 cm * 1 ft/12 in * 1 hr/60 min = 2.54 * 10^-4 ft/min
Therefore, Suzie the slug is traveling at a speed of 2.54 * 10^-4 feet per minute.
It seems like you've arrived at the correct answers. The speed of 0.45 mm/hr converts to 1.25 * 10^-7 m/s and 2.54 * 10^-4 ft/min using the given conversion factors. It's possible that the discrepancies among the answers given by different people could be due to rounding errors or small variations during the intermediate calculations. However, based on the conversion factors provided, your answers are accurate.
