Question

Total distance$=\_\_\_\_\_\_\_\_\times$Total time taken

Answer 1

1. The ratio of total distance travelled to the total time taken is called average speed.
2. Average speed=$\frac{\mathrm{Total}\mathrm{distance}\mathrm{travelled}}{\mathrm{Total}\mathrm{time}}$

Hence, Total distance travelled=$\mathrm{Average}\mathrm{speed}\times \mathrm{total}\mathrm{time}\mathrm{required}$.
