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:
1
Step-by-step explanation:
( 50 / 5² )² ÷ 4 (by PEDMAS, do the terms inside the parentheses first)
= [ (5 · 10) / (5 · 5) ]² ÷ 4 (the 5's cancel out in the numerator and denominator)
= [ (10) / (5) ]² ÷ 4
= [ 2 ] ² ÷ 4
= 4 ÷ 4
= 1
