Question

At the start of a journey a milometer in a car shows 43562 and at the end of the journey the distance

Answer 1

The upper bound is 267.9 and the lower bound is 226.1.

What is the upper and lower bound?

At the beginning of the journey, the possible values of the milometer before been rounded to the nearest mile are: 43,561.5, 43,561.6, 43,561.7, 43,561.8, 43,561.9, 43,562,43,562.1, 43,562.2, 43,562.3, 43,562.4

At the end of the journey, the possible values of the milometer before been rounded to the nearest mile are: 43,828.5, 43,828.6, 43,828.7, 43,828.8, 43,828.9, 43829, 43829.1, 43829.2, 43829.3, 43829.4.

Upper bound =  43,829.4- 43,561.5 = 267.9

Lower bound = 43,828.5 - 43,562.4 = 226.1
