Question

A rectangular field is 72 m by 58 m amar walks around it at the rate of 3 km per hour what time will he take in walking two round

Answer 1

length = 72 m
breadth = 58 m
perimeter = 2(l+b)

$= 2(72 + 58) \\ = 2(130) \\ = 260 \: m$


distance= 260 m
speed = 3 km /hr
$= 3 \times \frac{1000m}{3600s} \\ = 1000m \div 1200s \\ = 0.83 m {s}^{ - 1}$
time = distance ÷ speed

=260 m ÷ 0.83 m/s
=313.25 s
≈5 mins (approx)
