Question

Round your answers to the nearest whole number.

The fasted train in the world can travel 300 feet per second. How fast is this in miles per hour?

(1 mile = 5280 feet)

Answer 1

205 miles per hour.

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!

`= (1mi)/(5280ft) * (3600)/(1hr) * (300ft)/(1sec)`

`= (1,080,000)/(5,280)`

`= 204.454545...`

`= 205`

Answer:

205
