Question

The Rajdhani Express travels from Mumbai to Delhi a distance of 1384 KM it starts from Mumbai at 4:00 p.m. and reaches Delhi at 9 a.m. the next day what is its average speed​

Answer 1

Answer:

Distance=s=1384 km

time interval= 4:00 pm to 9:00 am

Let 4:00 pm be 1 hr.

After 12 hours half of the day is complete. So, after 12 hours the time would be 4:00 am. But, the final time is 9:00 am and time difference between 9:00 am and 4:00 am is 5 hours.

So the total time taken=12+5=17 hours

We know that, average speed = total distance travelled/total time taken

                                            =1384/17=81 km/h

hope it's helps you...
