A train sets off at 9:00 am at the speed of 70 km/h. Another train starts at 9:30 am in the same direction at the rate of 84 km/h. At what time will the second train catch the first train? | [
"12:00",
"12:30",
"1:00",
"11:30"
] | A | In thirty minutes the first train travels 35 km.
The second train catches the first train at a rate of 84 km/h - 70 km/h = 14 km/h.
The second train will catch the first train in 35/14 = 2.5 hours, so at 12:00 noon.

2(3x + 2x) = 2(4y + 3y)
5x = 7y
(5/7) * x = y
The ratio of the areas of the carpet in both cases:
= 3x * 2x : 4y * 3y
= 6x^2 : 12y^2
= x^2 : 2y^2
