Question

Look at the example problem above. Jeff's brother Rob ran the 40-yard dash in 4.95 seconds this year. How much faster did Rob run than Jeff?

Answer 1

Subtracting their times, it is found that Rob was faster than Jeff by 0.53 seconds.

• The problem is incomplete, we have that Jeff ran the 40-yard dash in 5.48 seconds.

• Rob ran in 4.95 seconds.

Rob ran in less time, so he was faster. To find by how much, we find the absolute value of the difference of their times, thus:

$|4.95 - 5.48| = |-0.53| = 0.53$

Rob was faster than Jeff by 0.53 seconds.
