Question

A train covers 360km in 3hours 20minutes. how much time will it take to cover a distance of 90km.

Answer 1

Answer:

50 minutes

Step-by-step explanation:

360 km -------------- 3 hours 20 min = 200 min

90 km   -------------- ?

360 * ? = 200 * 90

         ? = 200 * 90/360

         ? = 50 minutes

Answer 2

$x1 \div y1 = x2 \div y2 \ \\ \\ 320 \div (10 \div 3) = 90 \div y2 \\ \\ 96y2 = 90 \\ \\ y2 = 90 \div 96 = 15 \div 16 = (15 \times 60) \div 16 \\ \\ thus,y2 = 56min \: 25secs$
