Kevin said that if you triple his age the result will be 1 less than his mother age
Ivahew [28]
Basically, this problem is saying that if you multiply x by 3, then you will get a number that is one less than y. So, if you switch that around a bit, then the problem is saying that if you subtract 3x from y, you'll get 1. 

Your final answer should be y - 3x = 1.

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.
