Answer 1

Answer:

6,180

Step-by-step explanation:

marbles Rajat has = 7+5x = 37-7

30 = 5x

x=6

thus , Rohan has 6 marbles

7/7=630

7x = 630

x=630/7

x=90

2/7 =2x

2x=90*2

180

5x + 7 = 37

5x = 37-7

5x = 30

x = 30/5 = 6

She covered by running = 1-2/7

=>5/7 of track

track length = 630 m

5/7 * 630
