140 miles
1600 / 80 = 20 hours by train 1600 / 200 = 8 hours by plane it will take 20 - 8 = 12 hours more by train
speed = distance/time = 100mi/2h = 50mi/h
Just divide the distance by the time.
Plot distance vertical axis and time on horizontal and draw a graph with the first train leaving at zero time plot distance travelled in 4 hours I.E. 300miles draw a line. For second train start from 2 hours on time line and plot distance travelled in 4 hours I.E. 500 and draw line where they intercept draw a line to distance scale horizontally answer 375miles from the station.
140 miles
281 1/4 km.
It will take you about 12 hours, and 14 minutes to travel from Chennai to Nagercoil by direct train, a distance of 701 km.
180 miles

1600 / 80 = 20 hours by train 1600 / 200 = 8 hours by plane it will take 20 - 8 = 12 hours more by train
A train that travels at 40 kilometers per hour (kph) for 10 hours goes 400 kilometers. If the train goes 50 kph for 8 hours, it also travels the same 400 kilometers. The difference in speeds is 10 kph, and the difference in times is 2 hours.
454 km
Distance = (speed) x (time) (x - 2) (x + 9) = ( x2 + 7x - 18 ) miles
3 hours and 36 minutes.
speed = distance/time = 100mi/2h = 50mi/h
Just divide the distance by the time.
