Step-by-step explanation:

45 km in 54 minutes.

5 km in 54/9 mins

70 km in 54/9* 70

             = 420 mins

            = 7 *60mins

             = 7hrs

20 bars of chocolate cost Rs 320

5 bars of chocolate cost Rs 320/4

35 bars of chocolate cost Rs 320/4 * 7

                                               = Rs 540

40 m of cloth is Rs 2000

10 m of cloth is Rs 2000/4

50 m of cloth is Rs 2000/4 * 5

                           = Rs 2500
