Step-by-step explanation:

The total distance the boy can travel is 560 miles.

Step-by-step explanation:

Given,

The boy travels with 28 miles per gallon,

That is the distance travel by him for a gallon = 28 miles,

Also, the original quantity of gas he has = 10 gallon,

And, he buys more gas for $1.75 per gallon.

Let x be the quantity of gas bought by him,

⇒ Cost of gas he bought = 1.75x dollars,

According to the question,

1.7x = 17.50 ⇒ x = 10

Thus, he bought 10 gallon gas,

Total quantity of gas he has = 10 + 10 = 20 gallon,

Hence, the distance travelled by him with 20 gallon = 20 × 28 = 560 miles.
