J. Aditya left his house at 9:20 am, and travelled at 75 krohr. His brother left later and travelled along the
same road at 90 km/hr. They both arrived at the same destination at 3:20p.m. At what time did Aditya's
brother leave home?​

Answer 1

Answer:

10:20 AM

Step-by-step explanation:

Time taken by aditi/Aditya = 3:20 Pm - 9:20 Am = 6 hr

Speed of Aditi/Aditya = 75km/Hr

Distance = 75*6 = 450 km

Speed of Aditi/Aditya 's Brother = 90 km/Hr

Time Taken by Aditi/Aditya 's Brother = 450/90 = 5 Hr

So he left at 10:20 AM
