Question

A train travels 200 km in 1 hour and 50 minutes. What's his average speed?

Answer 1

Given

Distance, d=200 km

Time taken , t=1 hr 50 min=1.83 hr

To find

The average speed

Step-by-step explanation

We know speed is the ratio of distance by time

Thus,

`\begin{gathered} v=(d)/(t) \\ v=(200)/(1.83)=109.28\text{ km/hr} \end{gathered}`

Conclusion

The average speed is 109.28 km/hr
