Speed
Riding speed = 9 mph
Driving speed = 27 mph
Time
If x hours is the time taken when riding, (x - 1/3) hours is the time taken when driving.
Distance in both instances is the same, D= Speed * time
Therefore,
9*x = 27(x-1/3)
9x = 27x - 27/2
9x = 27x - 9
(9-27)x = -9
-18x = -9
x = 9/18 = 1/2 hours
Distance, D = 1/2 *9 = 4.5 miles
240cm is the correct answer
Reason:
Answer:
A. Probability of Russell = 12/37 or 32.4% (Rounding to the next tenth)
B. Probability of Peter = 5/74 or 6.8% (Rounding to the next tenth)
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Guard Forward Center Totals
Over 6 feet 25 30 30 85
Under 6 feet 130 120 35 285
Totals 155 150 65 370
2. Russell is 5'9". What is the probability he is a forward?
Probability = Number of forwards under 6 feet/Total number of players
Probability = 120/370
Probability = 12/37 or 32.4% (Rounding to the next tenth)
3. Peter is 6'2". What is the probability he is a guard?
Probability = Number of guards over 6 feet/Total number of players
Probability = 25/370
Probability = 5/74 or 6.8% (Rounding to the next tenth)
Hope this helps you!!!!! :D
