Answer» circular PATH radius = 150 m total time take to COVER = 9 minutes for this we have to find circumference circumference = 2πr => 2πr=> 2*3.14*150 => 6.28*150 => 942 MSO, the PERSON travel 942 m in 9 min distance travel in 1 min = 942/9 => 104.66 m distance travel by MAN in 3 min = 3×104.66=> 319.98m hence the man will travel 319.98 m in 3 min |
