A car from a to B, the first hour line 14, the second hour line 518, two hours line 114 kilometers. How many kilometers between a and B?
A: the distance between a and B is 216 km
A car from a to B, the first hour of the whole line 1 / 4, the second hour of the whole line 5 / 18, two hours of 114 kilometers, thousands of meters in length
114/(1/4+5/18)=216
How long is the 114 km highway from the first hour to the second hour
Total length: 114 △ 1 / 4 + 5 / 18 = 114 △ 19 / 26 = 216 km
A car drives from a to B. on the first day, it takes 1 / 5 of the whole journey, wakes up 100 kilometers the next day, and has 7 / 15 of the whole journey left. How long is the whole journey
Total length:
100 ÷ (1-5 / 1-15 / 7)
=100 △ 1 / 3
=300 km
