Answer:
B
Step-by-step explanation:
Though it is not obvious, the c belongs in the numberator, not the denominator.
So C and D are both wrong.
9: 3 * 3
3: 3
4:2 * 2
Lowest common denominator = 2 * 2 * 3 * 3
Lowest common denominator = 36
B
Answer:
Cost to travel 75 miles = 11.55 $
Explanation:
A scooter can travel between 22 and 28 miles on each gallon of gasoline.
Average distance a scooter can travel with each gallon of gasoline = (22+28)/2 = 25 miles.
One gallon of gasoline costs between $3.75 and 3.95 per gallon.
Average cost for one gallon of gasoline = (3.75+3.95)/2 = 3.85 $
We need to find cost for traveling 75 miles.
Gasoline required = Total miles/ Average distance a scooter can travel with each gallon of gasoline
= 75/25 = 3 gallons.
Cost to travel 75 miles = Gasoline required x Average cost for one gallon of gasoline
= 3 x 3.85
= 11.55 $
To now the difference you just have to subtract and will give you 1.68
Answer:
Ravi’s average speed is 7 miles per hour
Step-by-step explanation:
In this question, we are tasked with calculating what Ravi’s average speed was.
We must know that the term average speed is mathematically equal to Total distance/ Total time
We already have the time of 3 hours, what is needed is the distance.
From the question, we can see that they met at the point where Pilar had travelled 55 miles. What this means is that Ravi would have traveled (55-34) miles to this point since they are coming in opposite direction. This means that Ravi had traveled 21 miles
Thus his average speed is 21 miles/ 3 hours = 7 miles per hour
76 cents. ($0.76)
(sum of purchases = $12.16 divided by 0.0625 = .76)
