PLS HELP IF YOU WANT Chelsea takes the bus to school, but she walks home. The bus travels to the school at an average speed of 45 miles per hour. While going home from school, Chelsea walks at a speed of 2.5 miles per hour.
In total, she takes 1 hour to travel to school and back. If t is the time it takes to go to school by bus, the equation that will help find the time it takes Chelsea to get to school on the bus is ANSWER1
. The equation will have ANSWER2
PLS ANSWER ANSWER 1 AND 2

45 * t = 2.5 * (1-t)...the equation will have one solution.

Step-by-step explanation:

For this case, the first thing you should know is:

d: v * t

Where,

d: distance

v: speed

t: time

To go to school by bus we have:

d = 45 * t

To return from school we have:

d = 2.5 * (1-t)

how the distance is the same:45 * t = 2.5 * (1-t)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
