A robot moving forward at a constant speed takes 2.5 hours to travel 1 kilometer. Moving forward at this same constant speed, it
makvit [3.9K]

Answer:

The length of the hallway is 10 m.

Step-by-step explanation:

Given:

Time taken to cover 1 km = 2.5 hours

Distance covered in 2.5 hours = 1 km

Therefore, speed of robot = \frac{\textrm{Distance}}{\textrm{TIme}}=\frac{1}{2.5}=0.4\ km/h

Now, speed is constant.

Now, time taken to cover the length of hallway = 90 s

Speed of the robot = 0.4 km/h

Converting 0.4 km/h to m/s, we multiply by the factor \frac{5}{18}. This gives,

0.4\times \frac{5}{18}=\frac{1}{9}\ m/s

Now, distance of the hallway is equal to the product of speed and time. So,

Distance of hallway = Speed \times Time

Distance of hallway = \frac{1}{9}\times 90=\frac{90}{9}=10\ m

Therefore, the length of the hallway is 10 m.

What is the x in 120(2x-2)=240
coldgirl [10]

Answer:

X=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

120(2x−2)=240

(120)(2x)+(120)(−2)=240(Distribute)

240x+−240=240

240x−240=240

Step 2: Add 240 to both sides.

240x−240+240=240+240

240x=480

Step 3: Divide both sides by 240.

240x /240 = 480 /240

x=2
