Answer 1

Answer:

A. 69.5 hrs

B. 36 hrs

C. 123 hrs

D. 442.5 hrs

Step-by-step explanation:

A.  Given,

    Speed = 60 km/hr

    Distance = 4170 km

    As we know,

    Time = Distance/Speed

    Time = 4170/60                 (transferring 60 to LHS)

             = 69.5 hrs

B.  Distance = 2160 km

    Speed = 60 km/hr

    Time = Distance/Speed

    Time = 2160/60

             = 36 hrs

                 

C.  Firstly, E to G means E to F and F to G

    Distance = EF + FG

                    = (4830 + 2550) km

                    = 7380 km

    Speed = 60 km/hr

    Time = Distance/Speed

    Time = 7380/60

             = 123 hrs

D.  Total Journey = AB + BC + CD + DE + EF + FG + GA

     Total Distance = (4170 + 3410 + 2160 + 8140 + 4830 + 2550 + 1290) km

                              = 26550 km

     By using same formula

     Time = Distance/Speed

     Time = 26550/60

              = 442.5 hrs
