Question

Round your answers to the nearest whole number.

Answer 1

Answer:

205  miles per hour.

Step-by-step explanation:

1 mile = 5280 feet so:

300 ft / second = 300/ 5280 miles/second.

There are 3600 seconds in an hour so

this converts to  300 * 3600 / 5280 miles per hour

= 204.55 miles per hour.

Answer 2

Hey!

-----------------------------------------------

Solution:

Let's use dimensional analysis!

$= \frac{1mi}{5280ft} * \frac{3600}{1hr} * \frac{300ft}{1sec}$

$= \frac{1,080,000}{5,280}$

$= 204.454545...$

$= 205$
