A woman starts from her home at 9.00 a.m., walks with a speed of `5 km h^(-1)` on straight road up to her office 2.5 km away, stays at the office up to 5.00p.m. and returns home by an auto with a speed of `25 km h^(-1)`. Choose suitable scales and plot the x-t graph for her motion.

Text Solution

Verified by Experts

Given, speed of woman `s_1 = 5 km h^(-1)`
Distance travelled by her = `d_1 = 2.5 km`
Speed of auto, `s_2 = 25 km h^(-1)`
Time taken in reaching office = `("distance")/("speed") = (d_1)/(s_1) = 30` min
Time taken in returning from office = `(d_1)/(s_2) = 6 ` min.
