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
Answer:
Step-by-step explanation:
Let n = the number of prints
and C = the total cost.
At the regular price, the formula is
C = 1.45n
During the promotion, you must pay for the first nine prints: 9 × 1.45 = 13.05.
For anything over nine prints (n - 9), you must pay $13.05 plus the promotional cost of $1.10 for each print. The promotional formula is
C = 13.05 + 1.10(n - 9) {n > 9}
1. Calculate the cost of 19 prints
2. What number of the prints is a waste of money?
During the promotion, buying fewer than nine prints would be a waste of money, because you would not be taking advantage of the promotional savings.
