Answer:

Total time taken by walking, running and cycling = 22 minutes.

Step-by-step explanation:

Let the speed of walking = x

As given,

The distance of walking = 1

Now,

As $Time = \frac{Distance }{Speed}$

⇒ Time traveled by walking = $\frac{1}{x}$

Now,

Given that - He runs twice as fast as he walks

⇒Speed of running = 2x

Also given distance traveled by running = 1

Time traveled by running = $\frac{1}{2x}$

Now,

Given that - he cycles one and a half times as fast as he runs.

⇒Speed of cycling = $\frac{3}{2}$ (2x) = 3x

Also given distance traveled by cycling = 1

Time traveled by cycling = $\frac{1}{3x}$

Now,

Total time traveled = Time traveled by walking + running + cycling

= $\frac{1}{x}$ + $\frac{1}{2x}$ + $\frac{1}{3x}$

= $\frac{6+3+2}{6x} = \frac{11}{6x}$

If he cycled the three mile , then total time taken = $\frac{1}{3x}$ + $\frac{1}{3x}$ + $\frac{1}{3x}$ = x

Given,

He takes ten minutes longer than he would do if he cycled the three miles

⇒x + 10 = $\frac{11}{6} x$

⇒ $x - \frac{11}{6} x = -10$

⇒ $-\frac{5}{6}x = -10$

⇒x = $\frac{60}{5}$ = 12

⇒x = 12

∴ we get

Total time traveled by walking + running + cycling = $\frac{11}{6} x = \frac{11}{6} (12) = 11 (2) = 22$ min

Write the equation of a circle with a center at (12, 6) and a radius of 6.

uranmaximum [27]

Answer:

(x-12)² + (y-6)² = 36 (Option C)

Step-by-step explanation:

use circle formula

(x-h)² + (y-k)²= r²

h= 12 and k= 6 and r= 6

(x-12)² + (y-6)² = 6²

6 squared = 36 (6·6)

(x-12)² + (y-6)² = 36

Kerry is on the cross country team. She runs 3 miles every day except on her birthday. How many miles does she run each year?

Marina86 [1]

Answer:

1,092 miles

Step-by-step explanation:

There are 365 days in a year. Subtract 1 day because of her birthday. So what you're going to do is multiply 3 times 364 which equals 1,092.

So Kerry runs 1,092 miles each year.

1/150 : 2 = 1/200: X

NeTakaya

Answer:

The value of X is $X=\frac{3}{2}$

Step-by-step explanation:

Given : $\frac{1}{150} : 2=\frac{1}{200} : X$

To find : The value of X ?

Solution :

$\frac{1}{150} : 2=\frac{1}{200} : X$

Converting ratios into fraction,

$\frac{\frac{1}{150}}{2}=\frac{\frac{1}{200}}{X}$

$\frac{1}{150\times 2}=\frac{1}{200\times X}$

Cross multiply,

$200X=300$

$X=\frac{300}{200}$

$X=\frac{3}{2}$

Therefore, The value of X is $X=\frac{3}{2}$
