What we know :
After m minutes, and adult blinks about 10m+3 times.
1 hour= 60 minutes
What we need to find:
About how many times does an adult blink in 3 minutes? In 2hours?
m=3
f (m)=10m+3
f (3)=10 (3)+3
=30+3
=33
An adult blinks 33 times in 3 minutes
2hours=2×60=120minutes
f (120)=10 (120)+3
=1200+3
=1203
An adult blinks 1203 times in 2 hours.
