Givens
The bullet is going at sniper-rifle level speeds so let's assume Barrett M82 which goes at 928 m/s.

Rose is 7.24 meters away from the target

We are going to use this scientific article that gives us measurements about the human head. The Mean (The most common) measurement of the Bitragion breadth (The straight line distance between the right and left tragion landmark on the cartilaginous flaps in front of each ear hole is measured.) is 13.2 cm.

Distance Moved
For this calculation the camera is gonna be our friend. Assuming it doesn't move is gonna be our assumptions.

81 px for picture one, and 50 px for picture two is our width of the face. picture one has a height of 428 px and picture two has a height of 267 px. Anglesizing will be used to find the angle for later use in our calculation.

Picture one: 2atan(tan(70/2)*(81px/428px)) = 0.178862709 rad = 10.248078338002 degrees

Picture two: 2atan(tan(70/2)*(50px/267px)) = 0.17699518 rad = 10.14107680818 degrees.

Using this angular size calculator we can find the distance traveled between the two frames by comparing the distance from the camera and the guy moving.

Picture one = 73.603 cm from the camera

Picture two = 74.384 cm from the camera

74.384 - 73.603 =  0.781 cm is our depth movement. And due to the two-dimensional art style it is impossible to to know if he has moved more or not.

cm to m brings us to 0.00781 meters.

Speed Calculation
(Distance the character moved) x (Speed of projectile) / (Distance the projectile was away from the character)) = Speed

(0.00781) x (928) / (7.24) = ...1.00106077 m/s... Ok yeah, this is not gonna happen with this art style... or I'm just incompetent.... possibly both.
