A train travels 180 km in 3 h. Find its speed in km/h. Class 7
A train travels 180 km in 3 h. Find its speed in: Class 7
(i) km/h
(ii) m/s
(iii) What distance will it travel in 4 h if it maintains the same speed throughout the journey?
Answer:
Distance =180 km, Time =3 h
(i) Speed = [latex]\frac{\text { Distance }}{\text { Time }}=\frac{180 \mathrm{~km}}{3 \mathrm{~h}}[/latex] = 60 km/h
(ii) Speed in m /s = 60 × [latex]\frac{5}{18}[/latex] = 16.67 m/s
(iii) Time = 4h, Speed = 60 km/h
Distance = Speed × Time
= 60 km/h 4 × 4h
= 60 × 4 = 240 km
