Ответ:
1. Equation are,
d(t)= 6 t+2 is the equation for team A
and, d(t) = 6 t is the equation for team B
2. No , team B will not catch up to team A.
Step-by-step explanation:
Here, Team A is traveling 6 miles per hour and is 2 miles ahead of Team B.
x represents the number of hours
Then the total distance covered by A in t hours,
d(t)=6 t+ 2
And, Team B is also traveling 6 miles per hour.
Therefore, the total distance covered by B in t hours is,
d(t)= 6 t
Since, the speed of both teams are equal and already team A is 2 miles ahead of team B.
Therefore, for catching up to team A team B must be increase its speed.
Otherwise, It can not catch up team A.
