Billy walked 52 miles in 3 days how many miles could he walk in 10 days?

He could walk  173 miles in 10 days

Step-by-step explanation:

To solve this problem let us use the ratio method

∵ Billy walked 52 miles in 3 days

∵ We need to find how many miles could he walk in 10 days

→ Use the ratio method

→ Miles  →  Days

→  52     →   3

→   x       →   10

→ x is the number of miles

→ By using cross multiplication

∵ x × 3 = 52 × 10

∴ 3x = 520

→ Divide both sides by 3 to find x

∴

∴ x = 173 miles

∴ He could walk  173 miles in 10 days
