Answer:
He has run 40 yards.
Step-by-step explanation:
A football playing field is usually 100 yards long. That means, the mid-field will be 50-yard line.
If a player carries the ball from his team's 15-yard line to the opposing team's 45-yard line, it means he first runs from his team's 15-yard line to the mid-field line and then from mid-field line to the opposing team's 45-yard line.
So, the distance from his team's 15-yard line to the mid-field [tex]=(50-15)= 35[/tex] yards.
and the distance from the mid-field to the opposing team's 45-yard line [tex]=(50-45)= 5[/tex] yards.
Thus, the total distance he has run [tex]= (35+5) = 40[/tex] yards.
