10(3) + 3 = 33 times in 2 minutes
10(120) + 3 = 1203 times in 2 hours

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.
