Answer:
990 km
Step-by-step explanation:
their speed ratio = 45: 60 = 3 : 4
so their time ratio will be = 4 : 3
(speed is inversely proportional to time )
difference in time taken = 5hr 30 min
= 5h + 1/2h =11/2
time taken by each train = 4×11/2 = 22hr by slower train &
3 × 11/2 = 16.5 hrs by faster train .
total distance = s × t = 45 × 22 = 990 km
Second method: , d/ s = t
(x/45) - (x/60) = 11/2 => x = 990 km
