Answer:
The film animator can draw 16 sketches in 3 hours
The film animator can draw 37 1/3 sketches in 7 hours
Step-by-step explanation:
4 sketches = 45 minutes
3 hours = 180 minutes
x sketches = 180 minutes
4 : 45 = x : 180
4 / 45 = x / 180
Cross product
4*180 = 45 * x
720 = 45x
x = 720 / 45
= 16
The film animator can draw 16 sketches in 3 hours
how many drawings can be completed in 7 hours ?
7 hours = 420 minutes
x sketches = 420 minutes
4 : 45 = x : 420
4 / 45 = x / 420
Cross product
4*420 = 45*x
1680 = 45x
x = 1680 / 45
= 37 15/45
= 37 1/3 sketches
The film animator can draw 37 1/3 sketches in 7 hours
