On Mary's walk she covered the 3-mile distance to the park in one hour. However, the return trip took her one and a half hours. What was her average speed for the round trip?

Answers

the total distance covered by Mary is 6miles
total time spent is 2 and half hours
average speed is given by,total distance divided by total time
so,6/2.5=2.4miles per hour

Final answer:

Mary's average speed for the round trip was 2.4 miles per hour, calculated by dividing the total distance of the trip (6 miles) by the total time for the trip (2.5 hours).

Explanation:

The question deals with calculating average speed for a round trip. The total distance for Mary's walk was 6 miles (3 miles to the park and 3 miles back). The total time taken for the walk was 2.5 hours (1 hour to get to the park and 1.5 hours to return).

Average speed is calculated by dividing total distance by total time. So, the average speed of Mary's round trip is 6 miles divided by 2.5 hours, which equates to 2.4 miles per hour.

Find three consecutive even integers such that the sum of the smallest to the largest 36

Answers


If they were all the same integer, then each one would be
1/3 of 36, and you would have

                                           12  +  12  +  12  =  36 .

But you don't want them to all be the same number.  You
want them to be three consecutive even numbers.

Fine !  Take 2 away from the first 12, and glue it onto the last 12 .
Their sum doesn't change, but now you have

                                             10  +  12  +  14  =  36 .
First, I would set up an equation (assuming 36 is the sum of all 3 numbers). 

x+(x+2)+(x+4)=36
               3x+6=36
                   -6   -6
                   3x=30
                   ---   ---
                   3     3
                   x=10

Now, we just plug in the numbers to find the consecutive integers
10+(10+2)+(10+4)
10+12+14

So your 3 consecutive even integers are 10,12 and 14
