Q. In a decrement timed drill, at the sound of a fire alarm it took a fire fighter 9.5 seconds to reach the Fire pole, 3.2 seconds to slide down the pole, 13.6 to put on protective gear, 5.7 to climb aboard the truck. How long did it take the fighter to be ready and aboard the truck?

A. Do I just add them all up and and divide 4 by the answer?
why divide? Just add up all the times.
Dividing by 4 will give the average time per activity, but no one asked for that.
Dividing 4 by the sum is meaningless. It gives the number of activities that can be done in a second, but that's of no use to anyone.
Oh so just adding? Thanks!
To find the total time it took for the firefighter to be ready and aboard the truck, you need to add up the individual times. Let's go through the steps:
1. Add the time it took to reach the fire pole (9.5 seconds).
2. Add the time it took to slide down the pole (3.2 seconds).
3. Add the time it took to put on protective gear (13.6 seconds).
4. Add the time it took to climb aboard the truck (5.7 seconds).
5. Sum up all these times to get the total time.
So, the calculation would be:
9.5 + 3.2 + 13.6 + 5.7 = ?
Add the numbers together:
9.5 + 3.2 = 12.7
12.7 + 13.6 = 26.3
26.3 + 5.7 = 32
The total time it took for the firefighter to be ready and aboard the truck is 32 seconds.
