Answer:

167.2 m/sec

Step-by-step explanation:

Convert 602 km/hr to m/sec, as follows:

602 km       1000 m

------------ * ----------------- = 602,000 m/hr

    hr               1 km

602,000 m          1 hr

------------------ * ---------------- = 167.2 m/sec

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.
