A car at 45 kilometers per hour from a to B, 3 hours a journey of 57, how many kilometers does the car have to travel to reach B?

A car at 45 kilometers per hour from a to B, 3 hours a journey of 57, how many kilometers does the car have to travel to reach B?

45 × 3 ÷ 57-45 × 3 = 189-135, = 54 (km). A: it will take 54 km for this car to reach the second place

A car from a to B at a speed of 65 kilometers per hour, driving 3 hours can reach B, then in the form of T (0 less than t less than or equal to 3) hours from a () km, from B () km

A car from a to B at a speed of 65 kilometers per hour, driving 3 hours to reach B, then in the form of T (0 less than t less than or equal to 3) hours from a (65t) kilometers, away from B (65 × 3-65t) kilometers

A car went from place a to place B at a speed of 65 kilometers per hour for 5 hours, 5 / 12 of the whole journey. How many kilometers is the distance between a and B

65 × 5 △ 5 / 12 = 780 (km)
A: the distance between a and B is 780 km

The car drove from place a to place B at the speed of 65 kilometers per hour. After 2.4 hours, it was 31.5 kilometers away from place B. the road between the two places was more than 1000 meters long

2.4×65+31.5
=156+31.5
=187.5 km
It is 187.5km long
