Answer 1

Answer:

i hope it is going to help u

Answer 2

We know that ,

If the distance increases ,time taken increases in same proportion.

So time taken and distance varies directly, for the same speed .

$\begin {tabular} { | c | c | c | }</p><p>\cline {1-3} Distance travelled (x) & 540 km & 980 km\\</p><p>\cline {1-3} Time taken (y) & 9 hours & ? \\</p><p>\cline {1-3}</p><p>\end {tabular}$

$So, \frac{x_{1}}{y_{1}} = \frac{x_{2}}{y_{2}},\\Here , \: x_{1} = 540 , \: y_{1} = 9 ,\\</p><p>x_{2} = 980 , \: y_{2} = ?$

$By \: substituting , \\\frac{540}{9} = \frac{980}{y_{2}}$

$\implies y_{2} = \frac{980 \times 9 }{540} \\= \frac{49}{3} \\= 16 \frac{1}{3} \:hours$

Therefore.,

$\green { The\:bus \:travels \:980 \:km \:in \:16 \frac{1}{3} \:hours }$
