A person on a moving sidewalk travels 40 feet in 8 seconds. The moving sidewalk has a length of 200 feet. How long will it take

beks73 [17]

Answer:

The man covers 200 ft in 40 seconds.

Step-by-step explanation:

A person is moving on the sidewalk from one end to the other end.

He walks 40 feet in 8 seconds.

Therefore his speed = $\frac{distance covered}{time}$

= $\frac{40}{8}$

= 5 ft/ $s^{2}$

He covers the sidewalk distance at a rate of 5 feet every second.

To calculate the time taken to cover 200 ft,

time = $\frac{distance to be covered}{speed}$

time = $\frac{200}{5}$

<u>time = 40 seconds</u>

Hence the man covers 200 ft in 40 seconds.

HELP FAST PLEASE! FOR BRAINLIEST!!

Gekata [30.6K]

Answer:

1. C-surface area

2. The formula V = B x h is not suitable, because the surface area of wrapping paper needed to be calculated, not the volume.

V = Ph + 2B = 15x(5+6+9) + 2x 9x3/2 = 327

3. B: Base area

H: Height of solid

4. She said V =220, while V_real = 7x6x4 =168

=> She is wrong

5. Check the Pythagorean theorem 3^2+4^2 =9+16 =25 =5^2

=> Right triangle.

=> Area = 3x4/2 =6
