Question 692 Marks
A bus can cover $64.5\ km$ in an hour. How much distance can it cover in $18$ hours$?$
Answer
View full question & answer→Distance covered by the bus in $1\ h = 64.5\ km$
$\therefore$ Distance covered in $18\ h = (64.5 × 18)\ km = 1161\ km$
Hence, the bus can cover a distance of $1161\ km$ in $18\ h$
$\therefore$ Distance covered in $18\ h = (64.5 × 18)\ km = 1161\ km$
Hence, the bus can cover a distance of $1161\ km$ in $18\ h$
