Answer: Aisha is less than 43 inches tall right now.
Explanation:
Let x be the present age of Aisha,
And, she grows 5 inches during the next year,
⇒ Her age in next year = x + 5
Aisha needs to be at least 48 inches tall to ride,
Thus, for riding next year,
x + 5 ≤ 48
But, According to the question,
Next year Aisha will still not be tall enough to ride.
⇒ x + 5 < 48
⇒ x < 48 - 5
⇒ x < 43
⇒ Her present age is less than 43 years.
