If a football player carries the ball from his team's 15-yard line to the opposing team 45-yard line, how far has he run

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 yards.

and the distance from the mid-field to the opposing team's 45-yard line yards.

Thus, the total distance he has run yards.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
