km/hr respectively. If the fast train reaches 5.30 hours before the slow train

then what is the total distance?

By Ava

Answer:954 km

Step-by-step explanation:both train should be travel same distance

let time taken by slow train be T

time taken by fast train T- 5.3

45 × T = 60(T-5.3)

T = 53×6/15 = 106/5

distance covered = 106/5× 45 = 954 km
