Answer:
1, Width: 4cm
1st time: 4x2=8
2nd time: 8×2=16
3rd time: 16x2= 32
4th time: 32x2=64
So the final width of the photo is 64cm.
2,3 hours = 180 minutes
15 minutes = 2 bacteria
30 minutes = 4 bacteria
45 minutes = 8 bacteria
60 minutes = 16 bacteria
75 minutes = 32 bacteria
90 minutes = 64 bacteria
105 minutes = 128 bacteria
120 minutes = 256 bacteria
135 minutes = 512 bacteria
150 minutes = 1024 bacteria
165 minutes = 2048 bacteria
180 minutes = 4086 bacteria
195 minutes = 8192 bacteria
210 minutes = 16384 bacteria
225 minutes = 32768 bacteria
240 minutes = 65536 bacteria
255 minutes = 131072 bacteria
270 minutes = 262144 bacteria
285 minutes = 524288 bacteria
300 minutes = 1048576 bacteria
For every 15 minutes, multiply the bacteria twice.
So in 3 hours, there are 1,048,576 bacteria.
