Question

5. are triangular field is 90 m by 70 m a man walks around it at the rate of 4 kilometre per hour what time will he take to make only one round around it​

Answer 1

Perimeter of the rectangle is 90 + 90 + 70 +70 = 160 + 160 =320 m

In km we have 320/1000 = 0.320 km because 1000m = 1 km

So his speed - 4 km / hr = 4 km / 60 min =

5“f：plies5(0.320) = 1.km So if 1 km is 15 min then 1.6 km

15 x 1.6 min = 24 min

Hence the person takes 24 min .
