Question. Ricciana and Margarita joined in their school's long jump event. Ricciana ran and jumped a total of 24 feet - 20 feet for running and 4 feet for jumping. Margarita ran for 18 feet and jumped 1 foot less than twice Ricciana's jump. How much farther did Margarita run and jump than Ricciana?
Answer. 1
What step-by-step reasoning justifies that answer?
Reasoning: Twice the distance of Ricciana's jump is 4 x 2 = 8 feet. So, Margarita jumped 8 - 1 = 7 feet. Margarita ran and jumped for 18 + 7 = 25 feet in all. So, Margarita ran and jumped 25 - 24 = 1 foott more than Ricciana.
