Answer 1

A car travels 30 kilometers for 30 minutes. the car then stop at a service station fir 10 minutes the car continues for another 20 minutes at a constant speed of 45m/s. draw the distance -time graph fir the car?$45 \frac{m}{c} = 45\times3.6=162\frac{km}{h} ; S = v\times t=162\frac{km}{h}\times \frac{1}{3}=54;54+30=84$
