Homework Statement
Martin won the 400 metre race in a time of 1 minute
The time was correct to a tenth of a second
The distance was correct to 1cm
Find the upper and lower bounds of Martin's speed in km/h
Homework Equations
Speed = distance over time
The Attempt at a Solution
400 = 0.4km to 1 cm it's 0.4005 or 0.3995
1 second = 0.00277777777777 hours
how do I find the upper and lower bounds for a tenth of a second from the number above (it's recurring).
THe upper bound of speed = upper bound of distance/lower bound of time
The lower bound of speed = lower bound of distance/upper bound of time
Thanks
