Answer:
Option (2)
Explanation:
Option (1).
Time taken by Tina to walk = 56 minutes
Time taken by her sister to walk the same distance = x minutes
If both the sisters take the same time to walk, then
x = 56 minutes
Option (2).
Let the height of Tina = x inches
and the height of her brother = 56 inches
if Tina is shorter than her brother then,
x < 56 inches
Option (3).
Tina's dog weighed two months ago = 56 pounds
If the dog gained the weight in two months then weight before 2 months will be less than the present weight.
Let the weight of her dog is x pounds now,
x > 56 pounds
Option (4).
Amount with Tina = $x
Cost of the camera = $56
If the money with Tina has enough money to buy the camera, then the amount of money with her will be higher than the cost of the camera.
x > $56
Option (2) will be the answer.
