In 1925, the Tri-State Tornado ripped a 219 mi path of destruction through Missouri, Illinois, and Indiana, killing a record 695 people. The maximum winds in the tornado were 318 mph. Express the wind speed in km/h and in ft/s.

Solution

Solution:

Wind speed is given as 318 mph

we know that 1 miles is equal to 1.60 km

therefore 318 mph will become 511.71 km/h

Similarly,

1 miles is equal to 5280 feet

therefore 318 mph will become 318 x 5280 feet/h

= 318 x 5280/3600 feet/s (1 hour = 3600 s)

= 466.4 ft/s
