Answer:
Distance covered by car 180 km in 5 hours
(i) Distance covered in 1 hour = \frac { 180 }{ 5 } = 36 km
Distance covered in 3 hours = 3 x 36 = 108 km
(ii) To cover a distance of 180 km, time taken = 5 hours
To cover a distance of 1 km, time taken = \frac { 5 }{ 180 }
To cover a distance of 54 km, time taken = \frac { 5 }{ 180} x 54 = 1.5 hours
