L Lucky New member Jan 24, 2010 #2 Jodie gets 7km far from javier per hour. therefore it needs three hours to get away by 21 kms.......... (72 - 51) Jodie created this distance in the same time in which Javier crossed 51 kms. this means Javier's speed was 51/3 km/hr i.e. 17 km/hr and Jodie was at 17 + 7 = 24 km/hr
