Answer 1

$\bf\large\underline\pink{Solution:-}$

Distance = 2592 km

Let the speed be x km/h

The number of hours needed = x/2

Find the time:

Time = Distance ÷ Speed

x/2 = 2592 ÷ x

x/2 = 2592/x

cross multiply:

x² = 5184

x = √5184

x = 72

Find the time:

Time = x/2

Time = 72/2 = 36 hours

Answer: The car will need 36 hours to cover 2592 km
