Answer 1

First of all convert 2 minute 20 sec. into sec. total time = 2*60+20 ......2*60sec. +20. 120 sec+20sec. =140 sec ........ in 40s no. Of round made=1 . So, 1/40*40 =3.5 ABC is a right angled triangle in which AC is the hypotenuse. So, (AC)2 = (BC)2 ............. (AC)2 = (10)2 + (10)2 ......(AC)2 = + .......... (AC)2 = 200 .....AC = under root 200.................AC =14.143 answer..
