A plane flies 15 miles in 20 seconds. How long would it take the plane to cover 30 miles?

Answer 1

Answer:it would take the plane 40 seconds

if you multiply by two then you would be able to get 30

like 15 times 2 and since it’s 15 miles to 20 seconds or 15:20 you would have to multiply by the same number.
