A girls' track team must run 3 miles on the first day of practice and 6 miles every day after that. The boys' team must run 5 miles every day of practice. The coach will order new javelins at the end of the day that each girl's total mileage surpasses each boy's. How many total miles will each girl have run by the time the coach orders the new equipment?

The 4th day so 21 miles the girls would have to run

Each girl would have ran a total of 21 miles and boys would have ran a total of 20 miles by the end of the fourth day before the couch order new javelins.

Step-by-step explanation:

Girls track team

First day of practice=3 miles

Days afterwards = 6 miles

Boys track team

Everyday = 5 miles

coach will order new javelins at the end of the day that each girl's total mileage surpasses each boy's.

First day

Each girl total mileage = 3 miles

Each boy total mileage = 5 miles

Second day

Each girl total mileage = 3miles+6miles=9 miles

Each boy total mileage=5 miles+5 miles = 10 miles

Third day

Each girl total mileage = 3+6+6=15 miles

Each boy total mileage=5+5+5=15 miles

Fourth day

Each girl today mileage = 3+6+6+6=21 miles

Each boy total mileage=5+5+5+5 = 20 miles

Difference=girls-boys

=21-20 = 1 mile

The fourth day is the day each girl's total mileage (21 miles) surpasses each boy's total mileage (20 miles) with a total of 1 mile
