Thomas has constant speeds for both running and walking. When a down-escalator is moving, Thomas can run down it in 15seconds or walk down it in 30seconds. One day, when the escalator was broken (and stationary), it took Thomas
20seconds to run down it.

How long, in seconds, would it take Thomas to walk down the broken escalator?

amswer is 7mph

Step-by-step explanation:

i said so

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
