Reena travels 450 km to her home partly by train and partly by bus. She takes 8 hours if she travels 150 km by train and the remaining by bus. If she travels 300 km by train and the remaining by bus, she takes 1 hour less. Find the speed of the train and the bus separately​

ans fast I will mark you brainliest !!

Answer 1

Step-by-step explanation:

let the speed of bus X kilometre per hour and speed of the train y kilometre per hour.

150/y + 300/x = 8

300/y + 150/x = 8-1 = 7

600/y + 300/x = 14

450/y = 6

y = 450/6 = 75

x = 50

the speed of bus 50 kilometre per hour and speed of the train 75 kilometre per hour.
