Calculate the speed of a car that travels 150 metres in 10 seconds. Express your answer in km/h. Class 7
Answer:
Distance =150 m
Time taken =10s
Speed = [latex]\frac{\text { Distance covered }}{\text { Time taken }}[/latex]
= [latex]\frac{150 \mathrm{~m}}{10 \mathrm{~s}}[/latex]
= [latex]\frac{150}{1000}[/latex] km ÷[latex]\frac{10}{3600 \mathrm{~h}}[/latex]
Speed in km/hr = 54 km/h
