Answer:
I think if it takes me 8 hours then it will surely take him 8 hours
Answer:
40/3 hrs = 13.3 hrs
Step-by-step explanation:
Let me = K , my brother = P
K digs a hole in 8 hrs
K in 1 hr digs 1/8 of a hole
K + P dig a hole in 5 hrs
K + P in 1 hr dig 1/5
Let the portion of the hole Plan digs in 1 hr be x
1/8 + x = 1/5
x = 3/40
3/40 of the hole is dug by P in 1 hr
1 of the hole is dug by P in 40/3 hrs
= 40/3 hrs
=13.3 hrs
