Help me answer the problem with complete solution. I need the answer as soon. Thank you for helping me.

5. At 1:00 P.M., a thermometer reading 70°F is taken outside where the air temperature
is – 10°F (ten below zero). At 1:02 P.M., the reading is 26°F. At 1:05 P.M., the ther-
mometer is taken back indoors where the air is at 70°F. What is the thermometer
reading at 1:09 P.M.?
A bacterial population B is known to have a rate of growth proportional to B
itself. If between noon and 2 P.M. the population triples, at what time, no controls
being exerted, should B become 100 times what it was at noon?
