Answer 1

Stop A and Stop B

Explanation:

Data for a Trolley

Stops Distance Time

From Stop A to Stop B 150 meters 50 seconds

From Stop B to Stop C 200 meters 50 seconds

From Stop C to Stop D 360 meters 60 seconds

From Stop D to Stop E 280 meters 40 seconds

From definition: speed = distance/time

• Speed From Stop A to Stop B : 150/50 = 3 m/s

• Speed From Stop B to Stop C : 200/50 = 4 m/s

• Speed From Stop C to Stop D : 360/60 = 6 m/s

• Speed From Stop D to Stop E : 280/40 = 7 m/s
