Answer :
(a) The speed is, 186.287 mi/hr
(b) The speed is, 83.277 m/s
(c) The speed is, 273.22 feet/s
Explanation :
(a) We are given the speed is, [tex]299.8km/hr[/tex]
As we know that,
[tex]1km=\frac{1}{1.60934}mi[/tex]
By using both the conversion, we get:
[tex]299.8km/hr[/tex]
[tex]\Rightarrow \frac{299.8km}{1hr}\times \frac{1mi}{1.60934km}[/tex]
[tex]\Rightarrow 186.287mi/hr[/tex]
The speed is, 186.287 mi/hr
(b) We are given the speed is, [tex]299.8km/hr[/tex]
As we know that,
[tex]1km=1000m[/tex]
and,
[tex]1hr=3600s[/tex]
By using both the conversion, we get:
[tex]299.8km/hr[/tex]
[tex]\Rightarrow \frac{299.8km}{1hr}\times \frac{1000m}{1km}\times \frac{1hr}{3600s}[/tex]
[tex]\Rightarrow 83.277m/s[/tex]
The speed is, 83.277 m/s
(c) We are given the speed is, [tex]299.8km/hr[/tex]
As we know that,
[tex]1km=3280.84feet[/tex]
and,
[tex]1hr=3600s[/tex]
By using both the conversion, we get:
[tex]299.8km/hr[/tex]
[tex]\Rightarrow \frac{299.8km}{1hr}\times \frac{3280.84feet}{1km}\times \frac{1hr}{3600s}[/tex]
[tex]\Rightarrow 273.22feet/s[/tex]
The speed is, 273.22 feet/s
