Answers
Step-by-step explanation:
time=3 hours
Maratha=5 hours
ans=34.92km/hr
Given : martha and saraha leave block p and q towards q and p respectively simultaneously travel in the same route .
after meeting each other on the way sarha takes 3 hrs to reach her destination while martha takes 5 hrs to reach her destination.
the speed of sarha is 40 km per hr ,
To Find : what is the speed of martha
Solution:
Let say they meet after t hrs
Distance covered by sarha = 40t km
Distance covered by martha = xt km x is the speed of Martha
After that
Distance covered by sarha = Distance covered by martha in next 5 hrs
=> 40t = 5x
Distance covered by martha = Distance covered by Saraha in next 3 hrs
=> xt = 40(3)
=> xt = 120
xt = 120
40t = 5x
=> x/40 = 120/5x
=> x² = 960
=> x ≈ 30.98
speed of martha ≈ 30.98
