James knows that when he walks, he takes about 120

Tpy6a [65]

Answer:

speed of James is: 3.75 miles/hour.

Step-by-step explanation:

We need to find the speed of James in miles per hour(mi/hr)

we know that 1 mile=5280 feet

James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.

i.e. he takes 7200 steps in 1 hour.

also each step of James=2.75 feet

total distance covered by James in 1 hour=2.75×7200 feet=19800 feet

$19800feet=\frac{19800}{5280} miles=3.65miles$

hence speed of James= (distance covered by james in 1 hour)/1 hour

speed of James=3.75 miles/hour.

If you need carpet that is 6 1/2 long and 5 3/4 wide how many square feet do you need for the carpet??

Orlov [11]

Find the area

A= l*w

A = (6 1/2) * (5 3/4)

6 1/2 = (2*6+1)/2 =13/2

5 3/4 = (4*5+3)/4 = 23/4

A = 13/2 * 23/4
