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

diego is collecting dimes and nickels for penny war he has collected $22.25 this represented by the equations 0.10x + 0.05y =22.

dlinn [17]

One solution is x = 1 and y = 443 because

0.10(1) + 0.05(443) = 22.25.

So, (1, 443) is a solution.

Since, 1 dime = 2 nickels,

Increment of 1 in x-value = Decrease of 2 in y-value.

Therefore, the set of possible solutions are {(1, 443), (2, 441), (3, 439), (4, 437),......(222, 1)}
