Answers
Answer:
He will take to perform the journey of 450 miles in 9 days of 8 hours each.
Step-by-step explanation:
Given that:
A man can perform a journey of 275 miles in 4 days of 11 hours each. _______(1)
Let man will take to perform the journey of 450 miles in x days of 8 hours each. _______(2)
Formula used:
S1/(D1 × T1) = S2/(D2 × T2)
Where,
- S1 = Distance given in (1)
- D1 = Total days given in (1)
- T1 = Total hours given in (1)
- S2 = Distance given in (2)
- D2 = Total days given in (2)
- T2 = Total hours given in (2)
According to the question:
→ 275/(4 × 11) = 450/(x × 8)
→ 275 × x × 8 = 450 × 4 × 11
→ 2200x = 19800
→ x = 19800/2200
→ x = 9
