Answer:

Option E - None of these answers is reasonable.

Step-by-step explanation:

To find : Convert 17.42 m to customary units ?

Solution :

The customary units is defined as the measure length and distances in the customary system are inches, feet, yards, and miles.

The options belong to feet and inches.

We have to convert meter into inches, feet.

Meter into feet,

1 \text{ feet} = 0.3048 \text{ meter}

1 \text{ meter} = \frac{1}{0.3048}\text{ feet}

17.42 \text{ meter} = \frac{17.42}{0.3048}\text{ feet}

17.42 \text{ meter} = \frac{174200}{3048}\text{ feet}

17.42 \text{ meter} =57 \frac{464}{3048}\text{ feet}

17.42 \text{ meter} =57 \frac{58}{381}\text{ feet}

Now, Feet into inches

1 \text{ feet} = 12\text{ inches}

\frac{58}{381} \text{ feet} = 12\times \frac{58}{381}\text{ inches}

\frac{58}{381} \text{ feet} =\frac{232}{381}\text{ inches}

i.e.  17.42 \text{ meter} =57\text{ feet }\frac{232}{381}\text{ inches}

or 17.42 \text{ meter} =57'\frac{232}{381}''

None of these answers is reasonable.

Therefore, Option E is correct.

Answer:

  21.25 seconds

Step-by-step explanation:

In miles per second, the speed of the jet is ...

  (720 mi/h)/(3600 s/h) = 1/5 mi/s

The speed of the sound is the same:

  (1 mi)/(5 s) = 1/5 mi/s

Then the rate of closure between the airplane and the sound is ...

  (1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s

To find the time required to close a gap of 8 1/2 miles, we can use the relation ...

  time = distance/speed

  time = (8.5 mi)/(0.4 mi/s) = 21.25 s

The pilot will hear the thunder 21.25 seconds after the flash.
