Answer:
x=18, y= 6
Step-by-step explanation:
if x+y=24
x= 24- y
in second case
x= 3y
24_ y = 3y
24=4y
y= 6
hence x = 24 _6 = 18
Answer: 12 days
Based on the question, we have to list the multiples of 3 and 4. This will be:
3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40.
The lowest common multiple is 12.
It will take 12 days before Korey runs and swims again on the same day.
240 miles
Step 1
We find the constant rate at which the family travels
Speed(Rate) = Distance/Time
A Family travels at a constant rate and drove 420 miles in 7 hours.
Speed(Rate) = 420 miles/7 hours
= 60 miles per hour
Step 2
If they drive at the same speed ,How many miles will they drive in the next four hours.?
We are to finally calculate the distance for the next 4 hours
Distance = Speed × Time
Speed = 60 miles per hour
Time = 4 hours
Distance = 60 miles per hour × 4 hours
Distance = 240 miles
Therefore, for the next 4 hours the number of miles they would drive is 240 miles
