Initially we can display the ratio as:

72:36.

Both numbers are divisible by 36 as that is your highest common factor for both.

72/36 = 2
36/36 = 1

After simplification, we get the answer of 2:1

30 miles per hour.3,520 feet per minute.who runs faster and by how many miles per hour? There 5,280 feet in one mile

Anvisha [2.4K]

First let's convert 30 miles to feet.

30 x 5,280 = 158400

Now let's find how many feet the first person runs per minute.

158400/60 = 2640

The first person runs 2,640 feet per minute, and the second person runs 3,520 feet per minute.
Since the second person runs fast, let's find by how many miles per hour they're faster than the first person.

3520-2640 = 880
How many miles is 880 feet?
5280/880 = 0.17

The second person runs faster by 0.17 miles per hour.

Hope this helps! :)

Answer:

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = $\frac{a_{2} }{a_{1} }$ = $\frac{\frac{10}{3} }{10}$ = $\frac{10}{3}$ × $\frac{1}{10}$ = $\frac{1}{3}$ → C
