Answer» Answer: Answer: 160 Step-by-step explanation: To prove: Total time taken = Time taken to cover 1st part + Time taken to cover second part Let the DISTANCE TRAVELLED in 2nd part (80kmph) be 160km then, The distance travelled in 1st part (30kmph) = Total distance - Distance travelled in 2nd part (in 80kmph) = 250 - 160 = 90 Therefore, Distance = Speed x Time. Similarly, Time = Distance / Speed 1st part (30kmph): Time = 90 / 30 = 3hrs 2nd part (80kmph): Time = 160 / 80 = 2hrs Time taken for 1st part + 2nd part = 3 + 2 = 5hrs =Total time taken Therefore, LHS = RHS Hence ANOOP covered 160km in 80kmph. |
