Answer:
Nhan reach town B at 13:24 pm
Step-by-step explanation:
Let
Speed of Nhan=3x km /hour
Speed of Phoung=4x km/hour
After 5 hours,
Distance covered by Nhan=3x(5)=15 xkm
Distance covered by Phuong=4x(5)=20x km
Total distance covered by Nhan to reach town B=15x+102 km
Total distance covered by Phuong to reach town B=20x+52 km
Distance between town A and town B for both person is same therefore,
Speed of Nhan=3(10)=30 km/h
Speed of Phuong=4(10)=40 km/h
Total distance between town A and town B=102+15(10)=252 km
Time taken by Nhan to reach town B from town A=
Time taken by Nhan to reach town B from town A=
=8 hours 24 minutes
1 hour=60 minutes
Nhan reach town B at 13:24 pm
