A train covers 15km in 45 minutes
distance = 45km
time = 45 minutes = 45/60 = 3/4 hours
Speed = distance ÷ time
= 45 ÷ (3/4)
= 45 × 4/3
= 60 km/h
To convert km/h into m/s, multiply by 5/18
60 km/h = 60 × 5/18 = 300/18 = 16.67 m/s
distance = 45km
time = 45 minutes = 45/60 = 3/4 hours
Speed = distance ÷ time
= 45 ÷ (3/4)
= 45 × 4/3
= 60 km/h
To convert km/h into m/s, multiply by 5/18
60 km/h = 60 × 5/18 = 300/18 = 16.67 m/s
