btw troy truck has a 30 gallon gas tank and gets an average of 21 miles per gallon

asap plz i really need

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 =

                                                                                  = 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.
