Answer:
20 miles per hour
Step-by-step explanation:
Given that the train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hours, the car caught up
Which means that the car travelled the same distance in 3 hours as the train travelled in 9 + 3 = 12 hours
Let the distance be d
Given the speed of car is 80 miles per hour
We know that
d = 240 miles
Now for the train Average speed = total distance / total time taken
Average speed of the train = = 20 miles per hour
Answer:
the lcm of 15 and 18 is 90 and the gcf is 3
Step-by-step explanation:
multiple factors to get lcm and to get GCF Find the prime factorization of 15
15 = 3 × 5
Find the prime factorization of 18
18 = 2 × 3 × 3
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 3
Answer:
If you're aking how much one dish would cost it would be $8.64
Step-by-step explanation:
7, 4, 6, 5
In this order is least to greatest:
1. 7 dishes-11% tip
2. 4 dishes-20% tip
3. 6 dishes -14% tip
4. 5 dishes-17.5% tip
Answer: 44/7
Step-by-step explanation:
117=x4(11)*(4)=x*(7)
44=7x
Step 2: Flip the equation.
7x=44
Step 3: Divide both sides by 7.
7x7=44/7
x=44/7
