Question

A rectangular field is 120 metre long and 50 metre broad .Find the time taken by a man to walk from one of its corners to the opposite corner along the diagonal at the rate of 5 kilometre per hour

Answer 1

Answer:

Step-by-step explanation:

By Using Pythagoras Theorem:

BD²= BC² + CD²

BD²= 50² +  120²

BD²= 2500 + 14400

BD²= 16900

BD= √16900 =  130 Meters

Therefore, The distance from one of its corners to the opposite corner along the diagonal is = 130 meters

Time Taken By the Man To walk from One End to Another:

130m= 0.13 Km

Speed = Distance / Time

5= 0.13/Time

Time=  5 Kmph x 0.13 km

Time =  0.65 Hours =  39 Minutes
