Answer» e have given thatLet the TIME be 't'.If speed = 30km/hrThen it takes 10 MINUTES lateIf speed = 42 km/hrThen, it takes 10 minutes early.According to question, it becomes,30(t + 10) = 42t 10)30t + 300 = 42t - 42042t - 30t = 300 + 42012t 720t = 60So, the DISTANCE would be30(60 + 10)30 x 70= 2100 kmHence, distance is 2100 km. |
