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=
`(5280)/(1)* 40=211200ft`

The conversion used from feet to inches is:

1 ft = 12 in

211200ft =
`(12)/(1)* 211200=2534400in`

The conversion used from inch to cm is:

1 in = 2.54 cm

2534400in=
`(2.54)/(1)* 2534400=6437376cm`

The conversion used from cm to m:

100 cm = 1m

6437376 cm =
`(1)/(100)* 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 =
`(60)/(1)* 60=3600sec`

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

`40miles/hr=(64373.76)/(3600)m/sec=17.89m/sec`

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