Question

Two students measure their reaction times by seeing how many seconds it takes one of them to catch a yard stick that the other drops right above his hand. Suppose the radical √0.08 represents the time it takes one of the students to catch the ruler, and √0.18 represents the time it takes the other student to catch it.
It also asks to make an expression to represent the difference between the two reactions.

Please help!!

Answer 1

An expression for the difference between the two reaction times would be

√0.18 - √0.08. The result will be positive.
