If they school récord for they softball throw is 78 feet, about about much farther must Robert throw they ball yo Match the record

To find out how much farther Robert must throw the ball to match the school record of 78 ft, we need to calculate the difference between Robert's throw and the record throw.

Let's denote Robert's throw as R ft.

To determine the difference, we subtract Robert's throw from the school record:

78 ft - R ft = Difference

Since we don't have the specific value of Robert's throw, we are unable to calculate the exact difference. However, we can still determine the choices that are possible based on the given options.

a) 15 ft: If the difference were 15 ft, then Robert's throw would be 78 ft - 15 ft = 63 ft. However, this does not match the record of 78 ft.

b) 16 ft: If the difference were 16 ft, then Robert's throw would be 78 ft - 16 ft = 62 ft. Again, this does not match the record of 78 ft.

c) 18 ft: If the difference were 18 ft, then Robert's throw would be 78 ft - 18 ft = 60 ft. This still does not match the record of 78 ft.

d) 20 ft: If the difference were 20 ft, then Robert's throw would be 78 ft - 20 ft = 58 ft. Once again, this does not match the record of 78 ft.

Therefore, based on the options provided, we can conclude that none of the choices (a, b, c, d) match the distance Robert must throw to equal the school record of 78 ft.
