Answer 2

Correct Question:-

A bike rider has to cover a distance of 400 km in 10 hours. If he covers half of the journey in 60 percent of the total time. What should be its speed to cover the remaining distance in the time left?

Answer:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:

▪︎$\orange{Total\ distance\ to\ be\ covered = 400km}$

▪︎$\orange{Total\ Time = 10hours}$

▪︎$\orange{Distance\ cover\ in\ 60 percent\ of\ time = ½of\ the\ journey}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:

▪︎$\orange{Speed\ of\ bike\ to\ cover\ the\ remaining}$

$\orange{distance}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

$\pink{\bf{Time\ remaining}}$

$\pink{\bf{ = Total\ time - 60percent of\ total\ time}}$

$\pink{\bf{ = 40 percent\ of\ 10 hrs}}$

$\pink{\bf{ = 4 hours}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\green{\bf{Distance\ to\ be\ covered\ at\ remaining\ time}}$

$\green{\bf{= Total\ distance - ½ of\ total\ distance}}$

$\green{\bf{= 400km - ½ of 400km}}$

$\green{\bf{= 400 - 200km}}$

$\green{\bf{= 200km}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\red{\bf{Speed = Distance ÷ Time}}$

$\red{\bf{= 200km ÷ 4hrs}}$

$\red{\boxed{\bf{=50kmph}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Formula to be remembered:-

▪︎${\orange{Speed = Distance ÷ Time}}$

▪︎${\orange{Time = Distance ÷ Speed}}$

▪︎$\orange{Distance = Speed × Time}$
