3. A train travelled from Bristol to Bath. The train started from rest, and accelerated for 3 minutes to a speed of 46 km/h. The train then stayed at 46 km/h for 20 minutes. The train then decelerated for 4 minutes and came to a stop. Use the information to draw a velocity-time graph on the axis below. Assume all accelerations and decelerations are linear. 50 40 30 Speed (km/h) 20 10 10 15 20 25 30 Time (minutes) 4 . Alice went for a bike ride. She started from rest and accelerated for 8 seconds to a speed of 11 metres per second. She then stayed at 11 metres per second for a further 16 seconds. She then accelerated again for 6 seconds to a speed of 14 metres per second. She then stayed at 14 metres per second for a further 18 seconds. She then decelerated, coming to a stop after 12 seconds.
