Answer: a) To find the speed of Train A, we need to divide the distance traveled by the time taken:
Speed = Distance / Time
Speed = 520.4 km / 4.8 h
Speed ≈ 108.42 km/h
Rounding to the nearest whole number, we get:
Train A is traveling at 108 km/h (approximately).
b) To find the speed of Train B, we need to divide the distance traveled by the time taken:
Speed = Distance / Time
Speed = 72.1 km / 0.8 h
Speed ≈ 90.13 km/h
Rounding to the nearest whole number, we get:
Train B is traveling at 90 km/h (approximately).
