Lyn's speed is 3 miles per hour.
That is distance travelled in 60 minutes
= 3 miles
So, distance travelled in 25 minutes
= 3 * 25 / 60 miles
= 25/ 20 miles
= 1.25 miles
New speed of Lyn is 5 miles per hour
That is, for travelling 5 miles, time required = 60 minutes
So, for travelling 1.25 miles, time required = 60 * 1.25 / 5 minutes
= 60/ 4 minutes
= 15 minutes.
It will take her 15 minutes, if she runs at a speed of 5 mph.
Hope this helps ..!!
Answer:
10
Step-by-step explanation:
Distance = √(x2-x1)² + (y2-y1)²
d = √(10-4)² + (13-5)²
d = √6² + 8²
d = √36+364
d = √100
d = 10
Answer:
3,000
Step-by-step explanation:
Since the next number is less than 5 you round down
This question is worded badly, so don't be alarmed.
Obviously if this were a square patter the number of red tiles could only be 1,4,9,16,25,36 etc and this is not the numbers given...It would help tremendously if they gave you another reference point so as to know how the tiles were being laid out.
If they are laid out alongside one another with a consistent border for each you wouldn't need 12 blue tiles for each red tile either...if two were laid side by side you would only need 20 blue tiles to have the border around both...you see how the arrangement makes a huge difference and you are given no details as to what that arrangement is...
So just to keep it simple, assume that each red tile is surrounded by 12 blue tiles....
Total tiles equals r+12r=13r
t=13r so
t(15)=195, t(20)=260, t(25)=325, t(30)=390
