Answer:
At 11:30 am they will arrive at their starting point together
Step-by-step explanation:
we know that
One of them completes one lap in 6 minutes
The second one in 9 minutes
The third one in 15 minutes
step 1
Find the least common multiple (LCM)
6=2*3
9=3²
15=3*5
so
LCM=(3²)*(2)*(5)=90 minutes
step 2
Find the number of laps of each jogger for the LCM
jogger 1
90/6=15 laps
jogger 2
90/9=10 laps
jogger 3
90/15=6 laps
If they start at 10:00 am
then
10:00 am + 90 minutes=11:30 am
Answer: 120 Miles
Step-by-step explanation:
We start with $140.
The initial payment is $50.
$140 - $50 = $90
We now have $90 dollars to spend on miles.
$90/$0.75 per mil = 120 Miles
Using the remaining $90 we can drive 120 miles in a week.
I am 100% sure the answer is a.4
Because it was (2,3) then became (8,12)
2*4= 8 and 3*4= 12
The numbers 2 and 3 were multiplied by 4 to get 8 and 12
