a) she was travelling at 73.3335ft/s
b) Her speed in ft/s, if she were going the speed limit, is 51.33345ft/s
In order to determine the speed of Jaqueline, we will need to convert her speed in mph to ft/s
a) Using the conversion rate:
1mi/hr = 1.46667ft/s
Convert 50 mph to ft/s (50 mph is his average speed limit)
50 mph = x
Divide both expressions:
[tex]\frac{1}{50} =\frac{1.46667}{x}\\1 \times x = 50 \times 1.4667\\x= 73.3335ft/s[/tex]
Hence she was travelling at 73.3335ft/s
b) The given speed limit is 35mi/hr. Convert to ft/s
[tex]\frac{1}{35} =\frac{1.46667}{x}\\1 \times x = 35 \times 1.4667\\x= 51.33345ft/s[/tex]
Hence her speed in ft/s, if she were going the speed limit, is 51.33345ft/s
