Convert 2000 ft./min. to miles per hour round to the nearest 10th
Serggg [28]

Answer:

The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour .

Step-by-step explanation:

Given as :

The speed = s = 2000 ft per min

Now, ∵ 5280 feet = 1 miles

so, 1 feet = \dfrac{1}{5280} miles

∴ 2000 feet =  \dfrac{1}{5280} × 2000 miles

i.e 2000 feet = 0.378 miles

<u>Again</u>

∵ 1 minute = \dfrac{1}{60} hour

So, The speed in miles per hour

s = \dfrac{distance}{time}

∴ s = \frac{0.378}{\frac{1}{60}}

i.e s = 2.268 miles per hour

Hence, The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour . answer
