Which of the equations, where t is the time in hours and d the distance in miles, describe a speed faster than the speed of a Winchester bullet?

1,950t

2,000t

Step-by-step explanation:

hope my answer helped , feel free to ask more.

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)

60%
