Question
Axar covered 1/4th of the total distance at a speed of
25 km/hr. Then, he covered (1/2) of the remaining distance at a speed of 30 km/hr, and the rest of the distance at a speed of 25 km/hr. If the total time taken by Axar to cover the entire distance is 6 hours, determine the total distance he traveled.Solution
ATQ, Let the total distance covered by ‘Axar’ be ‘4a’ km ATQ, (a/25) + {3a/(2 × 30)} + {3a/(2 × 25)} = 6 Or, 60a + 75a + 90a = 9000 Or, 4a + 5a + 6a = 600 Or, 15a = 600 Or, a = 600/15 = 40 Therefore, total distance covered by ‘Axar’ = 4x = 4 × 40 = 160 km
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
181.87 ÷ 13.89 X 8.13 + ? = 11.852Â
(18.21)² - (12.9)² = 20% of 649.9 - ? + 400.033
(124.99)² = ?
