Question

a rectangular field is 75 m by 50 m . A person walks around it at the rate of 3 km per hour . What time will he take in completing 3 rounds.

Answer 1

Answer:

25 minutes

Step-by-step explanation:

Length of rectangular field = 75 m

Breadth of rectangular field = 50 m

Perimeter of rectangle = 2 ( l + b )

                                      = 2 ( 75 + 50 )

                                      = 2 * 125

                                      = 250 m

Speed of person = 3km/hr = 50 m/min

Distance = 5 * 250

               = 1250 m

Time taken = Distance / speed

                   = 1250 / 50

                   = 25 minutes

Hence, time taken by man to complete 5 rounds is 25 minutes.
