The length of the railway from a to B is about 1464 kilometers. A fast train from a to B takes five twelfth of the whole journey in five hours. How many kilometers are there from B?
1464 × (5 / 1-12)
=1464 × 7 / 12
=854 (km)
A: it's 854 kilometers away from B
A train runs 220 kilometers in three and one-third of an hour, and it takes two and one-fourth of an hour to get from a to B at the same speed. How long is the railway between a and B?
Three and one-third of an hour is 200 minutes, which leads to the train speed per minute. Two and one-fourth of an hour is 135 minutes. The distance between the two places is obtained by multiplying the speed per minute by 135
The railway between a and B is 840 km long. A train leaves from a to B at 5:30 p.m. on the first day, with an average of 70 km per hour. When does the train arrive at B?
840 △ 70 = 12 (hours), 5:30 + 12 hours = 17:30, a: the train arrives at B at 17:30
