steven traveled for 10 hours at a constant rate of 53 miles per hour. Stephanie traveled at the same distance at a constant rate of 48 miles per hour. How long did it take stephanie to travel the same distance as steven, write an equation to solve.

It took 11.04 hours  by Stephanie.

Step-by-step explanation:

Concept

distance = speed*time

time = distance/time

Given

for Steven

time  = 10 hours

speed = 53 miles per hour

Distance for steven = 53*10 = 530 miles

Now ,

as Stephanie also traveled the same distance as steven

Distance = 530 miles

speed = 48 miles per hour

time = 530/48 hour = 11.04 hours

Thus, It took 11.04 hours  by Stephanie.

In other way

since distance traveled by Steven and Stephanie are same

let time taken by Stephanie be x hours

Distance traveled by steven = Distance traveled by Stephanie

53*10 = 48*x

x = 530/48 = 11.04 hours

equation = 53*10 = 48*x

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

x+10

20
