Question 702 Marks
A bus can cover 64.5km 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 = 64.5km
$\therefore$ Distance covered in 18h = (64.5 × 18)km
= 1161km
Hence, the bus can cover a distance of 1161km in 18h
$\therefore$ Distance covered in 18h = (64.5 × 18)km
= 1161km
Hence, the bus can cover a distance of 1161km in 18h
