Tomos is a skier he completed a ski race in 2 min 6 seconds

Step-by-step explanation:

The complete exercise is: "Tomos is a skier he completed a ski race in 2 min 6 seconds the race was 525 m in length. Tomos assumes that his average speed is the same for each race. using this assumption, work out how long tomos should take to complete an 800 m race give your answer in minutes and seconds"

For this exercise you can use the following formula to find the average speed :

Where "d" is the distance and "t" is the time.

In this case, based on the information given in the exercise, you can identify that:

Since  he completed a ski race in 2 min 6 seconds, and 1 minute has 60 seconds, you ge that this time in seconds is:

Substitute these values into the formula to find the average speed:

The formula for the time is:

Knowing that Tomos assumes that his average speed is the same for each race, for the  800 meters race you can identify that:

So, substituting values into the formula and evaluating, you get that the time it takes him to complete this race is:

Convert from seconds to minutes:

Converting 0.2 minutes to seconds, you get:

Therefore:

345
