Answer:
14 is 24
13 is 1.4
Step-by-step explanation:
answer 14:
First you need to add 10.1 and 1.9.
Second you need to multiply the answer you got by 4.
Last you need to divide the answer you got from the first two steps by 2.
Answer 13:
First you need to add 0.6 plus 7.4 and then multiply it by 2 because it is squared by 2.
Next you minus 14 from the answer you got from the first steps.
10 is the answer................
Answer:
1:50 PM
Step-by-step explanation:
Left school at 10:38 AM,
took them 51 minutes,
38+51=89,
89-60=29,
so when they drove to the museum, it was 11:29 AM.
From here, they stayed at the museum for 1 hour and 26 minutes,
so they stayed at the museum until 12:55 AM since 29+26=55.
Now, it took them 55 minutes to drive back to the school,
so 12:55 plus another 55 minutes,
it's going to be 1:50 PM when Dale's class got back to school.
Answer:
7/6
Step-by-step explanation:
(7x/12)/(x/2)
=7/6
Let the slower runners speed be X kilometers per hour.
Then the faster runners speed would be X+2 kilometers per hour.
The formula for distance is Speed times time.
The distance is given as 30 kilometers and time is given as 3 hours.
Since there are two runners you need to add the both of them together.
The equation becomes 30 = 3x + 3(x+2)
Now solve for x:
30 = 3x + 3(x+2)
Simplify:
30 = 3x + 3x +6
30 = 6x + 6
Subtract 6 from each side:
24 = 6x
Divide both sides by 6:
x = 24/6
x = 4
The slower runner ran at 4 kilometers per hour.
The faster runner ran at 4+2 = 6 kilometers per hour.
