Randy, Sandy and Todd are my cousins and their combined age is 87 years. Randy is four times as old as Sandy, but Todd is actual

NISA [10]

Answer:

Randy is 48 years old

Sandy is 12 years old

Todd is 27 years old

<em></em>

Step-by-step explanation:

Given

Represent their ages with the first letters of their names:

$R + S + T = 87$

$R = 4 * S$

$T = 15 + S$

Required

Determine their individual ages

We'll solve the above equations using substitution method of simultaneous equations

Substitute 15 + S for T and 4 * S for R in $R + S + T = 87$

This gives:

$4 * S + S + 15 + S = 87$

$4 S + S + 15 + S = 87$

Collect Like Terms

$4 S + S + S = 87 - 15$

$6S = 72$

Divide through by 6

$S = 72/6$

$S = 12$

<em>This implies that Sandy is 12 years old</em>

Substitute 12 for S in $R = 4 * S$ and $T = 15 + S$

$R = 4 * 12$

$R = 48$

$T = 15 + 12$

$T = 27$

<em>This implies that Randy is 48 years old and Todd is 27</em>

A circular track is 1/4 mile long. Elena runs on this track, completing each lap in 1/20 of an hour. What is Elena's speed? Incl

svp [43]

Answer:

5 mph

Step-by-step explanation:

The relation between speed, distance, and time is ...

speed = distance/time

Filling in the given values, we find the speed to be ...

speed = (1/4 mi)/(1/20 h) = (1/4)(20/1) mi/h = 5 mi/h

Elena's speed is 5 miles per hour.
