Question

(a) what is the speed of each train?
train a: 50 m/s
train b: 45 m/s
train c: 35 m/s
(b) which train is the fastest?
train a train b train c
(c) how far does each train travel in 2 seconds?
train a: meters
train b: meters
train c: meters

Explanation:

Step1: Calculate distance for Train A

Use formula \(d = vt\) (distance = speed × time).
For Train A, \(v = 50\frac{m}{s}\), \(t = 2s\).
\(d_A=50\times2\)

Step2: Calculate distance for Train B

For Train B, \(v = 45\frac{m}{s}\), \(t = 2s\).
\(d_B = 45\times2\)

Step3: Calculate distance for Train C

For Train C, \(v = 35\frac{m}{s}\), \(t = 2s\).
\(d_C=35\times2\)

Answer:

Train A: \(100\) meters
Train B: \(90\) meters
Train C: \(70\) meters
