Step-by-step explanation:
6/16 is greater than 5/16. The bigger the number, the higher the probability.
Have a great day!
There are a couple of ways to think about this.
1) Weight the speed by the time and compute the weighted average.
(60*2.5 + 75*1.5)/(2.5 + 1.5) = 65.625
Her average rate of speed is 65.625 mph.
2) Consider distance and time.
distance = speed * time
distance₁ = speed₁ * time₁
distance₂ = speed₂ * time₂
total distance = distance₁ + distance₂
total time = time₁ + time₂
And the average speed is given by
average speed = (total distance)/(total time)
Using the above formulas, we have
distance₁ = 60 mi/h * 2.5 h = 150 mi
distance₂ = 75 mi/h * 1.5 h = 112.5 mi
total distance = 150 mi + 112.5 mi = 262.5 mi
total time = 2.5 h + 1.5 h = 4.0 h
average speed = (262.5 mi) / (4.0 h) = 65.625 mi/h
Bette's average rate of speed is 65.625 mph.

Answer:
The answer is 0.45 or if you want to put as a fraction 9/20
Step-by-step explanation:
You can use this equation to figure out for any number of seconds how many items the cashier can ring up.
For instance if you wanted to know if 100 seconds how many items could be rung up:
y = .45x
y = .45(100) This would be 45 items.
If you wanted to know how many items could be rung up in 10 seconds:
y = .45(10) This would be 4.5 items.
You could use this equation for any amount of time to figure out how many items could be rung up.
Answer:
1 1/4 cups
Step-by-step explanation:
3 3/4 cups = 3.75
1/3 = .33333
3.75 x .33333 = 1.25
1.25 = 1 1/4 cups
