Answer:a)117 hours b)4.875days.

Step-by-step explanation:

Using the formula

Speed =Distance / Time

Given Distance = 3 3/5 -mile

and Speed=2/65  miles per hour.

Time =Distance / Speed

Time = (3 3/5)/(2/65)

Time =18/5÷2/65

Time =18/5 x 65/2 =117 hours

Now 24 hours =1 day

therefore 117hours =(117hours x 1 day )/ 24 =4.875days.

If 110% of a number is 528, then the number is:
Anuta_ua [19.1K]

Answer:

c) 480

Step-by-step explanation:

Any percentage can be converted to a number ratio by dividing by 100%.

E.g. 100%/100% = 1

Following this concept, we can find the equivalent of 110% :

110%/100% = 1.1

Since 528 is 1.1 times the number we are looking for, we just need to divide 528 by 1.1 to find our number. This is because 1.1/1.1 = 1

528/1.1 = 480

Hope this helped!

fiasKO [112]

Answer:

5.497787144 miles

Step-by-step explanation:

Remember that circumference of a circle can be calculated with:

2\pi r

r=radius

We also know that the radius is just a half of the diameter.

So, the radius of the track is (1/2)/2=1/4 miles

Now, use the circumference of a circle formula to find how much she runs in 1 lap.

2\pi (\frac{1}{4} )

Simplify

\frac{\pi }{2}

This is how much she runs in 1 lap.

Multiply by 3.5 for 3 and a half laps.

\frac{\pi }{2}*3.5

The answer is around 5.497787144 miles.
