If Usain Bolt can run a marathon (26.2) in 2 hours and 15 minutes, how fast would he run if he ran at the same constant rate?

inn [45]

Answer:

The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon.

Step-by-step explanation:

Given as :

The Distance of marathon = 26.2 unit

The time taken to complete marathon = 2 hours and 15 minutes

= 120 + 15 = 135 minutes

Let The constant speed of Usain Bolt = S unit per minutes

So, Speed = $\frac{Distance }{Time}$

Or, S = $\frac{26.2 }{135}$

∴ S = 0.194 unit per minutes

Hence The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon. Answer

Maryam's rectangular bedroom is 9 feet by 12 feet. What is the diagonal distance from one corner to the opposite corner?

ra1l [238]

Create a right triangle with the the two legs being sides of 9 and 12...then use the Pythagorean theorem to solve

a^2 + b^2 = c^2

9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2

Square root both sides to get c = 15 feet.

Line one (7,-41) and (-15,113) what is the slope of line one

Firdavs [7]

Slope of the line is -7

Step-by-step explanation:

Step 1: Find slope of the line using formula, m = (y2 - y1)/(x2 - x1). Here, x1 = 7, y1 = -41, x2 = -15 and y2 = 113

⇒ m = (113 - -41)/(-15 - 7)

= 154/-22 = -7
