I would have to say -0.5 then positive 0.25 because the rule seems to be divide by -2.
Answer:
Monica will walk a total of 3km in 60 minutes given that she walked 1km in 20 minutes
Step-by-step explanation:
The correct question is given below;
Monica walked every day for exercise at a rate of 1 kilometer every 20 minutes. At this rate, how many meters can Monica walk in 1 hour? EXPLAIN how you found your answer
solution;
Now in this question, given the number of kilometers Monica walks in 20 minutes, we are now told to find the number of kilometers she will walk in 60 minutes.
Now to get this, the easiest way to this is to use a cross multiplication as follows;
1km = 20 minutes
xkm = 60 minutes
Kindly remember/ recall that in an hour we have 60 minutes so it is necessary to make the conversion to the unit to achieve consistency. You might want to convert 20 minutes to hours too , but it is better to have it in minutes
Now let’s make the cross multiplication;
1 km * 60 minutes = x km * 20 minutes
xkm = (1km * 60 minutes)/20 minutes
xkm = 60 km minutes/20 minutes
xkm = 3km
Total of 8 times
Distance is 0.25 miles
8 * 0.25 is 2 so a total distance of 2 miles
We know his avg swim rate to be 60 minutes per mile, meaning if he traveled 2 miles then we multiply it by 60 to get our total time taken.
60min/mile * 2 miles = 120 minutes total
So, step D is the same as what I've done to calculate the total time it will take Tristan to swim around the lake.
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10. That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5
Answer:
x = 15
Step-by-step explanation:
x = √{(25-16)×25}
x = √(9×25)
x = √225
x = 15
