Question

How much time can you save travelling diagonally instead of running 450meters south and then 650meters west. if your running speed is 5.0m/s.
pls help

Answer 1

The diagonal distance is
sqrt[(450)^2 + (650)^2] = 790.6 m

The distance running south and then west is 450 + 650 = 1100 m.

The saving is distance is 1100 - 970.6 = 129.4 m

The saving in time is that distance divided by 5 m/s.
