Total time taken for Beatrice and Amy is the same (1/2hr or 30min)
Knowing that the dist from mkt to shopping centre is 2km, let point 1 to point 2 be 'x', the remaining unknown dist is 2x.
Find the time taken with Amy speed (80km/h) from mkt to shopping centre.
Aftwards, the remaining time MUST BE spent on traveling two ways from mrt to home and home to mkt.
Hence, again using the speed of 80km/h, find the dist 2x thus x+2km is the total dist from homr to shopping centre.
