▬▬▬▬▬▬▬▬▬▬▬▬☟

➧ Initial speed u = 36 km/h

➾ 36 x 1000 / 3600 m/s
➾ 10 m/s 

➧ Final speed v => 54 km/h

➾ 54 x 1000 /3600 m/s
➾ 15 m/s

➧ Time => 10 s

➧ Acceleration a = (v - u) / t

➾ (15 - 10) / 10

➾ 5/10 = 0.5 m/s2

➧ Speed = ut + ½ at2

➾ 10 x 10 + ½ x 0.5 x 10 x 10m

➾ 100 + 25

➾ 125 m...✔
