Question

Giulio’s reaction times are measured in two games. In the first game his reaction time is 13 of a second.
In the second game his reaction time is 18 of a second.
Find the difference between the two reaction times.

Answer 1

Answer: 5/234 of a second

Step-by-step explanation:

Reaction time in 1st case 1/13 of 1 second = 1/13 second

Reaction in second case 1/18 of a second = 1/18

LCM of 13 and 18 = 234

1/13 = 18/234

1/18 = 13/234

Difference = 18/234 - 13/234

=> 5/234

Hence difference is 5/234 of a second.
