● Usual approximate journey of Anjali is 70 minutes.

● Let's suppose the usual time taken by Anjali be X minutes.

● After increasing high speed by 27.27%, she would reach her office 15 minutes early.

● So 100% percent is X minutes

● And 127.27% is X - 15 minutes

● Speed = distance / time

So distance = speed × time

● We know that distance to her office is constant.

So speed 1 into time 1 = 2 speed 2 x time 2

100 × x = 127.27 ( x - 15 )

127.27 x - 100 x = 127.27 ×15

X = 127.27 × 15 / 27.27 = 70

So time taken by Anjali will be approximately 70 minutes.
