Question

Carol and Juan were playing with Carol's new train set. They pushed the trains around the track. They tried four different

sections of track. The train had the slowest speed on which section of track?

A) Track 1
B) Track 2
C) Track 3
D) Track 4
​

Answer 1

Speed (m/s) = distance (metres) ÷ time (seconds)

For Track 1: 0.2 ÷ 2 = 0.1m/s

For Track 2: 0.2 ÷ 2 = 0.1m/s

For Track 3: 0.6 ÷ 6 = 0.1m/s

For Track 4: 0.4 ÷ 6 = 0.07m/s

The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.
