Question

A plane travels $5100km$ in $6$ hours. How far will it go in $4$ hours $36$ minutes

Answer 1

Let plane travel $x$ km in one hour

Given that

$speed\times time=distance$

$\Rightarrow 6x=5100$

$\Rightarrow x=850$

Given time $=$ 4hr 36 min $=$ 4.6 hrs

So required distance $=4.6x=4.6\times 850$

$=3910$

Thus the plane travels $3910km$ in $4hr36min$
