Question

A car travels 192 km in 4 hours with a
constant speed. How far can it travel in 8
hours?

please give correct answer not explation ​

Answer 1

Answer:

v=192/4=48km/hr

distance=48×8=384km

Answer 2

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\tt A \:car \:travels\: 192\: km\: in\: 4 \:hours\: with\: a\\\tt constant\: speed\:. How\: far\: can\: it\: travel\: in \:8\\\tt hours$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf {\boxed {\mathbb {GIVEN}}}$

• $\sf \bf Distance(d) =192\:km$
• $\sf \bf Time(t) =4\:hours$

$\sf \bf {\boxed {\mathbb {TO\:FIND}}}$

• $\sf \bf Distance\:travelled\:by\:car\:in\:8\:hours$

$\sf \bf {\boxed {\mathbb {SOLUTION}}}$

$\tt \underline {A\:car\:travels \:192\:km\:in\:4\:hours}$

$\tt \underbrace {Let\:distance\: travelled \:by\: car\: in \:hour\:be\:x}$

${\boxed {\boxed {\color {blue} {\sf \bf x=\dfrac{d}{t}}}}}$

• $\sf \bf x=distance\:travelld\:by\:a\:car\:in\:1\:hour$
• $\sf \bf d=distance\:travelld\:by\:a\:car\:in\:4\:hour$
• $\sf \bf t=time$

$\sf \bf {\underbrace {\overbrace {\color {orange} {Substitute\:the\:values}}}}$

$\sf \bf \implies x=\dfrac{192}{4}$

$\implies{\boxed {\color {green} {\sf \bf x=48\:km}}}$

$\therefore \tt \underline {Distance \:travelled \:by \:car\:in\:1\:hour=48\:km}$

-------------------------------------------------------------------

$\sf \bf{\underbrace {\overbrace {\color {purple} {Distance\:travelled\:by\:car\:in\:8\:hours}}}}$

$\sf \bf \implies 8 \times 48$

$\implies{\boxed {\boxed {\color {red} {\sf \bf 384}}}}$

$\therefore \tt {\underbrace {Distance \:travelled \:by \:car\:in\:1\:hour=48\:km}}$
