Mathematics
1 answer:

Answer:

<h2>-7 + 3(n - 1)</h2>

Step-by-step explanation:

(-4)-(-7) = -4 + 7 = 3

(-1)-(-4) = 3

2-(-1) = 3

then the common difference r = 3

and the first term is -7

since the nth term = first term + (n - 1)×r

then  the nth term = -7 + (n - 1)×3

                              = -7 + 3(n - 1)

Monica watch every day for exercise at a rate of 1 km every 20 minutes suppose medical walk in 1 km every 15 minutes how many me
Serga [27]

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
