Brooke and Lamont ran a half marathon broke finished in 1 hour 50 minutes Lamont finished in 100 minutes who has the faster time ?

Lamont

Step-by-step explanation:

Since there are 60 minutes in one hour, you take take away 60 minutes from the hundred and convert it into one hour.

100-60=40

As you can see, there are forty minutes left, so you add that to the hour, therfore, you know that Lamont ran for 1 hour and 40 minutes, which is faster than Brooke’s one hour and 50 minutes

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
