Answer 2

First let us take out the circumferences of both circles.

Radius of inner circle = 100m

∴Circumference of the inner track= 2πr

                                                        =2×3.14×100

                                                        =628m

Radius of outer track=102m

∴Circumference of outer track=2πr = 2×3.14×102 = 753.6m

Time taken by A = 1min 30sec = 90 sec

Time taken byb B = 1min 32 sec = 92 sec

Speed of A = Distance covered by A ÷ Time taken

                   = 628÷90

                   = 6.98 m/s

Speed of B = Distance covered by B ÷time taken

                   =753.6÷92

                   =8.19m/s

 Speed of A is smaller than the speed of B.

                  ∴B runs faster.
