For this case, the first thing you should know is that by definition:

t = \frac{d}{v}

Where,

t: time to travel the distance

d: distance traveled

v: speed

Therefore, substituting values we have:

t = \frac{26.22}{9.6}

t = 2.7h

Answer:

it takes him or her 2.7 hours to run at 26.22 mi marathon

A stack of logs has 27 logs on the bottom layer each subsequent layer has five fewer logs in the previous layer at the top layer
Alinara [238K]

Answer:

S=252logs

Step-by-step explanation:

bottom layer has a1 = 25

second layer has a2 = a1 - 1 = 24

third layer has a3 = a2 - 1 = a1 - 2 = 23

.

.

n-th layer has an an = a1 - n = 25 - n

the top layer contains an = 25 - n and we know that the top layer has 11 logs thus

25 - n = 11

n = 25 - 11

n = 14

there are 14 layers

the total number of logs is the sum of the first 14 members of the Arithmetic Progression 25, 24, 23, 23,.....11 where

an = 25 - n

Sn = (n/2)(a1 + an) and since n = 14

S14 = (14/2)(25 + 11) = 7*36 = 252

S14 = 252 logs
