A bus averages 60 mi/h traveling to its destination in the first half of its trip through an expressway and 72 mi/h in the second half traveling through a motorway. What is the bus's average speed for the entire trip rounded to the nearest tenth

Step-by-step explanation:

Given

During first half it travels with a speed of

During second half it travels with a speed of

Average speed is given by

suppose t is total time

distance travel in first half

distance travel in Second half

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
