Marta practices the long jump. She jumps the same distance on her first four jumps. Her last two jumps are 1 1/2 feet longer than her first four jumps. Her average jumps distance is 16 feet. The equation below represents the situation, where j is the distance of each of Marta's first four jumps. 4j + 2(j+ 1.5)=16

Average:

The average of a data set is given by the sum of all elements of the data set divided by the number of elements in the data set.

Marta's jumps:

First four of j.

Lax six are 1 1/2 feet longer = 1.5 feet longer, so j + 1.5.

Six jumps, average of 16.

What is the distance of each of Marta's first four jumps?

This is j. So

The distance of each of Marta's first four jumps is of 15.5 feet.
