Answer:
7 minutes
Step-by-step explanation:
When Rob climbed the Eiffel Tower today, he climbed 1,000 steps in 25 minutes.
Today
Steps : minutes = 1000 : 25
If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow
Let x = number of minutes it will it take Rob to climb the stairs tomorrow
Tomorrow
Steps : minutes = 280 : x
Equate both ratios
1000 : 25 = 280 : x
1000 / 25 = 280 / x
Cross product
1000*x = 25 * 280
1000x = 7000
Divide both sides by 1000
x = 7,000 / 1,000
= 7
x = 7 minutes

Since it is a right triangle, then a^2+b^2=c^2, and a=sqrt(c^2 - b^2),
a=sqrt(361-144)=14.73
the answer is 14.73
