Answer 1

Question=> A person is moving from a to b and other moving from b to a. They complete their journey in 2h5min and 3h after they meet.if speed of 2nd is10km/h

find the speed of 1st person.

Answer

14 सही 2/5

Step-by-step explanation:

2घंटा 5मिनट =2+5/60=(2+1/12) = 25/12 घंटे

दूसरे आदमी द्वारा तय दूरी = चाल×समय=10×3= 30 km

अतः पहले आदमी की चाल

= दूसरे द्वारा तय दूरी/पहले द्वारा लगा समय

= 30/(25/12)

= 30×12/25

=( 14 सही 2/5 ) km/h

Solution:-

distance covered by 2nd person

= time taken× speed = 3×10 km

since same distance covered by 1st person

=> speed of 1st person.

= distance covered by 2nd/ time taken by 1st

= 10×3/(2h5min)

= 30 / (25/12 hours)

=( 14 integer 2/5) km/hour
