The answer is 3 your welcome
20+12+15= 32+15 = 47 minutes in total
300 meters per minute
300 * 47 = 14100 meters in total
with this we can see the first race was 4/9 that distance meaning the first race was 6266.6 meters long
14100 - 6266.6 = 7833.3
2/5 of 7833.3 is 3133.32
therefore 7833.3 - 3133.32 will give the distance of the third part of the race
meaning of course the answer is 4699.98 or rounding up 4700 meters for the third race
It's hard to tell from the way the question is written.
-- If he has 5 pennies, then it doesn't matter how many he lost.
He has five of them.
-- If he has 5 pennies after he lost three of them, then there are
eight now, just like there were before, but he only has 5 of them.
-- If he had 5 pennies before he lost three, then there are still
5 pennies, but he only has two of them.
Hello!
Judging by the question you have provided I came to the conclusion that to find the speed at which the student runes in feet per minutes you need to first start off by converting the distance, 50 yards, to feet.
To do this you need to use the equation 3x=y. X being yards Y being feet.
Your equation should look something like this, 3(50 Yards)= Feet, and your answer should be 150 feet.
The next step is to see the distance the student runs in feet per second. To do this you need to divide the 150 feet by 6.1 seconds.
Your answer should be 26.23 feet per second.
Lastly you now need to see the distance the student would run if they ran for a minute.
To do this you need to multiply the feet per second by 60 (one minute).
Your answer should be ~1574 feet per minute.
Hope this helped!
