WebDownload the notes NCERT Exemplar Solutions: Motion & Time Download Q.4. A bus travels 54 km in 90 minutes. The speed of the bus is (a) 0.6 m/s (b) 10 m/s (c) 5.4 m/s (d) 3.6 m/s Ans: b Explanation: Speed = Distance / Time Distance = 54km = 54 x1000 = 54000m Time = 90 minutes = 90×60= 5400s Speed = 54000/5400 = 10 m/s Q.5.
