Answer:

It took Peter 28 minutes and 10.82 seconds to finish the race.

Step-by-step explanation:

We have that:

$t_{A}$ : Antonio = 28 min + 11.00 s (1)

$t_{J}$ : Julio = A - 0.08 s (2)

$t_{P}$ : Pete = J - 0.1 s (3)

Then, the time at which Pete finished the race is:

$t_{P} = t_{J} - 0.1$ (4)

By entering equations (1), (2), (3) into (4) we have:

$t_{P} = (t_{A} - 0.08) - 0.1$

$t_{P} = 28 min + 11.00 s - 0.18 s = 28 min + 10.82 s$

Therefore, it took Peter 28 minutes and 10.82 seconds to finish the race.

I hope it helps you!

How can knowing the gcf and lcm help you when you add subtract and multiply fractions?

Maksim231197 [3]

In order to add and subtract fractions, we must be able to find a common denominator.
The LCD, or least common denominator, is the LCM of the denominators. Once we've added, subtracted or multiplied fractions, we often have to simplify the fraction.
In order to do this, we divide the numerator and denominator by their GCF. This means we must be able to find the LCM and GCF in order to work with fractions.
