Question

The length and breadth of a rectangular field are 58m 6cm and 41 cm respectively how long wil a man take to move four time round the field if he walks at the rate of 2.5 metre per second

Answer 1

Answer:

Step-by-step explanation: Length  =58m 6cm

                                                           =58.06 m

                                             Breadth=41cm

                                                           =0.41m

        Perimeter of the field = 2(58.06+0.41)

                                              = 116.94m  

        Let the number of seconds be 'y'

                 y =  116.94   x    2.5

                    =  292.35 seconds

                    = 4.8725 minutes

                   

                                       

Answer 2

A man will take 187.104 seconds to move four time round the field if he walks at the rate of 2.5 metre per second

Step-by-step explanation:

Length of rectangular field = 58 m 6 cm = 58 m +0.06 m = 58.06 m

Breadth of rectangular field = 41 cm = 0.41 m

Perimeter of rectangular field = 2(l+b)=2(58.06+0.41)=116.94 m

Distance traveled in 1 round = 116.94 m

Distance traveled in 4 round = $116.94 \times 4 = 467.76 m$

Speed = 2.5 m/s

Time taken to cover 467.76 m = $\frac{467.76}{2.5}=187.104 seconds$

Hence  man will take 187.104 seconds to move four time round the field if he walks at the rate of 2.5 metre per second
