Answer:
Toy truck will drive 315 miles since last the tank was filled.
Step-by-step explanation:
BTW troy truck has tank of capacity = 30 gallons
Since the toy truck is half filled so gas in the tank = [tex]\frac{30}{2}[/tex]
                                         = 15 gallons of gas
Average of the toy truck is given as = 21 miles per gallon
That means in 1 gallon truck travels = 21 miles
Therefore in 15 gallons of gas truck will travel = 21 × 15
                                       = 315 miles
Toy truck will drive 315 miles since last the tank was filled.
