Teacher: 15 seconds after the buzzer, the teacher has 135 meters to finish. 32 seconds after he left the starting line, the teacher has run 50 meters left. Usian Bolt: 22 seconds after the buzzer, Usain has 189 meters to finish.36 seconds after the buzzer, he has 42 meters to finish. Who will win the race? How do you know? and What is the outcome of the race?

huh?

the teacher has run 50 meters left

the teacher has to run 50 meters more to finish*

Assuming that each runner left the starting line at the sound of the buzzer,

in 17 seconds, the teacher has run 85 meters.

in 14 seconds, Usain has run 147 meters.

Now you can figure each runner's speed. The time left to finish is distance/speed.

Now you have to add the remaining time to each runner's elapsed time to see who will end first.

I think you can tell who will win, since Usain's speed is almost twice as fast as the teacher's. But check to be sure.

To determine who will win the race between the teacher and Usain Bolt, we need to compare the distances they have to finish at different time intervals.

Let's analyze the information given:

For the teacher:
- 15 seconds after the buzzer, the teacher has 135 meters left to finish.
- 32 seconds after leaving the starting line, the teacher has 50 meters left to finish.

For Usain Bolt:
- 22 seconds after the buzzer, Usain Bolt has 189 meters left to finish.
- 36 seconds after the buzzer, Usain Bolt has 42 meters left to finish.

To compare their positions, we need to find the average speeds for both the teacher and Usain Bolt.

Teacher's average speed:
The teacher covers (135 - 50) = 85 meters in (32 - 15) = 17 seconds.
Therefore, the teacher's average speed is 85/17 = 5 meters per second.

Usain Bolt's average speed:
Usain Bolt covers (189 - 42) = 147 meters in (36 - 22) = 14 seconds.
Therefore, Usain Bolt's average speed is 147/14 = 10.5 meters per second.

Now, let's compare the positions at the same time and see who will reach the finish line first:

At 32 seconds after the buzzer, the teacher will have already covered 32 * 5 = 160 meters.
At 36 seconds after the buzzer, Usain Bolt will have covered 36 * 10.5 = 378 meters.

From the distances covered, we can see that Usain Bolt will reach the finish line first because he covers a greater distance in the same time interval.

The outcome of the race is that Usain Bolt wins.

Illiterate America speaks again! LOL!
