A tornado similar to the Jarrell tornado (but less powerful) moves

at an average speed of 5 m s-1. Calculate the duration of this tornado

in (a) seconds and also (b) in hours, minutes, and seconds, if this

tornado was an average EF3 tornado. Hint: use the average tornado path

length for EF3 tornadoes, and the average speed given above, to

calculate the duration of the tornado. Remember, Speed = Distance/time;

you may have to rearrange this equation to solve for the tornado

duration
