A car travels from city A to city B at a speed of 60 miles per hour and returns to city A at a speed of 40 miles per hour. If the total round trip takes 5 hours, what is the distance between city A and city B?
ATQ, Let the distance between city A and city B be x miles. Time taken to travel from A to B = x/60 hours Time taken to travel from B to A = x/40 hours Total time = x/60 + x/40 = 5 hours Solving for x, we get x = 120 miles.
24.99 × 32.05 + ? - 27.01 × 19.97 = 29.99 × 27.98
25.11 × 3.98 + 26.03 × 4.12 – 33.95 + 94.9 × 4.02 =?
320.98 + 49.99% of (261.09 + 138.98) = ?
8.992 + (5.01 × 4.98) + ? = 224.03
24.96% of 380 + ? – 169.99 = 149.99% of 80
3.98 × 29.67 ÷ 11.90 of √24.89 = ?% of 199.79
?% of 399.97 = 11.982 + 16.13 × 4.16 – 35.99
?% of [(12.96 × 40.05) + 25.08 × 18.96] = 17.96 × 22.05 + 3.05 × 66.96
1299.99 ÷ 20.21 = ? + 325.985 - (180 ÷ 6 × 24.03)
