Question

In the summer of 2016, many tourists taking selfies with buffalo were injured in Yellowstone National Park. If buffalo can run 40.00 miles per hour, what is that in meters per second? You must use appropriate significant figures to receive full credit (6 pts) 1 in = 2.54 cm, 100 cm = 1m, 12 in =1 ft, 5280 ft = 1 mile, 60 s = 1 min, 60 min = 1 hour.

Answer 1

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= $\frac{5280}{1}\times 40=211200ft$

The conversion used from feet to inches is:

1 ft = 12 in

211200ft = $\frac{12}{1}\times 211200=2534400in$

The conversion used from inch to cm is:

1 in = 2.54 cm

2534400in= $\frac{2.54}{1}\times 2534400=6437376cm$

The conversion used from cm to m:

100 cm = 1m

6437376 cm =  $\frac{1}{100}\times 6437376=64373.76m$

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 =$\frac{60}{1}\times 60=3600sec$

We are asked: 40 miles/hr = ? m/s

$40miles/hr=\frac{64373.76}{3600}m/sec=17.89m/sec$

Therefore, the speed in meters per second is 17.89 m/s
