Answer:
Step-by-step explanation:
first runs n+1 laps
and second runs n laps in the same time.
so (n+1)8=10n
10n=8n+8
10n-8n=8
2n=8
n=8/2=4
one lap=1 mile
4 laps=4 miles
4+1=5 laps=5 miles.
first runs 5 miles whereas second runs=4 miles.
Answer:
1800
Step-by-step explanation:
there are 60 seconds in a minute
so, 30 * 60 = 1800
Assuming that the balls are not replaced;

= 5/42
(the numbers are decreasing in the denominator as you are presumably taking out the red balls. In the denominator, there is one less ball each time since you took out a red one).
Therefore, the probability of selected 4 red balls consecutively without replacement is 5/42.
