Answer : The speed in meters per second is 17.89 m/s
Explanation :
The conversion used from miles to feet is:
1 mile = 5280 ft
40 miles= [tex]\frac{5280}{1}\times 40=211200ft[/tex]
The conversion used from feet to inches is:
1 ft = 12 in
211200ft = [tex]\frac{12}{1}\times 211200=2534400in[/tex]
The conversion used from inch to cm is:
1 in = 2.54 cm
2534400in= [tex]\frac{2.54}{1}\times 2534400=6437376cm[/tex]
The conversion used from cm to m:
100 cm = 1m
6437376 cm = [tex]\frac{1}{100}\times 6437376=64373.76m[/tex]
The conversion used from hour to min is:
1 hr = 60 min
The conversion used from hour to min is:
1 min = 60 sec
60 min =[tex]\frac{60}{1}\times 60=3600sec[/tex]
We are asked: 40 miles/hr = ? m/s
[tex]40miles/hr=\frac{64373.76}{3600}m/sec=17.89m/sec[/tex]
Therefore, the speed in meters per second is 17.89 m/s
