A train runs 68m, 127m, 208m, 312m and 535m in five successive minutes after its start and for next five minutes it runs with an average speed of 33 km/h. Find the total distance covered in ten minutes?

Explanation

for first five minutes, the distance = (68+127+208+312+535)/1000 = 5/4 km. For next five minutes, \(\text { distance }=5 \times 33 / 60=11 / 4 \mathrm{~km}\). Total distance = 11/4 + 5/4 = 4
