1. Unless your wristwatch is made of solid gold and weighs about 23 lbs then grams would be a better measurement.

2. Sandy's estimate is not entirely reasonable because there are 4 times as many inches in a foot than there are feet in a yard.

3. 4 meters will hardly get you across the street so I doubt Jonathan will ride his bike 4 meters to get to school.

Answer:

1)  50 grams

2) His estimate was right.

3) Jonathan's estimate is not reasonable.

Step-by-step explanation:

1)

" A wrist watch is a small watch that is attached to a bracelet or strap and is worn around the wrist "

The better estimate of the mass of a wrist watch is 50 grams and not 50 kilograms because it would be very difficult for someone to wear a heavy weight thing in their wrist.

Hence answer is 50 grams.

2)

There are 36 inches in 1 yard.

and there are 3 foot in 1 yard.

Hence, Sandy's benchmark was reasonable  that there are more inches than feet in one yard.

3)

Jonathan thinks that he rides his bicycle about 4 meters from his house to school each day.

As 4 meter is not a long distance so he won't have to use his bicycle to go to school.

Hence, Jonathan's estimate is not reasonable.
