Geri ran in a marathon race. it took her 3 hours and 28 minutes to run 26 miles. how many minutes did it take her to run 1 mile if she ran at the same rate for the whole race?

1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.

Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.

Divide her total time by total miles run:

208 minutes / 26 miles = 8 minutes per mile.

8 minutes per mile

Step-by-step explanation:

Geri ran in a marathon race.

It took her 3 hours and 28 minutes to run 26 miles.

1 hour = 60 minutes

we will convert the time into minutes

3 hour 28 minutes = (3 × 60) + 28

                               = 180 + 28

                               = 208 minutes

∵ Geri ran 26 miles in 208 minutes

∴ She ran 1 miles =

                            = 8 minute

Geri ran 1 mile in 8 minute.

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
