On her first stroke, maria hit a golf ball 140 yards 2 feet 9 inches. on her second stroke, she hit it 170 yards 1 foot 6 inches. how far did the ball go altogether?

311 yards, 1 foot and 3 inches.

Step-by-step explanation:

We know that 12 inches equals one foot.

We know that 3 feet equals one yard.

We will start adding up the inches, from these two quantities:

9 inches + 6 inches = 15 inches (but 12 inches equals one foot) = 1 foot and 3 inches.

Now we will add up the feet considering we have now one extra foot from our previous sum.

2 feet + 1 foot + 1 foot = 4 foot (but 3 feet equals one yard) = 1 yard and 1 foot.

Now we will add up the yards considering we have now one extra yard from our previous sum:

140 yards + 170 yards + 1 yard = 311 yards.

So our final answer is: 311 yards, 1 foot and 3 inches.
