14) A plant that floats on the surface of rural bodies of water is known as duckweed.
The initial mass of a population of duckweed
is 500 kg. The mass of the population triples
every 45 hours and can be represented by
the function m(t) = 500 * 3*
345, where t is
time in hours.
=
Determine how many hours would pass
for the duckweed to grow to a mass
triple the original size.

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
