A car travels 186 kilometers in 3 hours. According to this calculation, it takes 8 hours to travel from a to B. how many kilometers is the distance between a and B? (in proportion)
The distance between a and B is x km
x：8=186：3
3x=186*8
x=492
The distance between a and B is 156 km, and it takes two-thirds of an hour for a car to drive three eighth of its total length. At this speed, how long does it take for a car to complete the whole journey?
What's the formula
156 * 3 / 8 = 58.5km
60 * 2 / 3 = 40 points
58.5/40 = 1.4625 km / min
156 / 1.4625 = 106.67 points
How long is the road? How long is the road?
Scale, 11
140:2=X:5
A car runs 140 kilometers in 2 hours. At this speed, it runs 5 hours from a to B. how long is the highway between a and B?
A: the highway between a and B is 350 km long
