Five Friends on a Line — How Far Jood to Kerry?
Lesson 12 of 13
About this lesson
Draw the line: Felipe–Gina–Heng–Jood–Kerry. Felipe is 400 m from Heng. Gina is 3× as far from Felipe as from Heng, so Gina-Heng = 100 m. Jood is also 100 m from Heng on the other side. Heng-Kerry = 850 − 400 = 450 m. Jood-Kerry = 450 − 100 = 350 m.
