Question

A car travels 180 kilometre in 5 hours
how much time is required to cover 30 kilometre with the same speed ?​

Answer 1

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

Answer 2

Answer:

a 5 hours -30 =25 hours

the time is requered 25 hours to cover 30 kilometers

b 180 - 30 = 150

150 distance is covered in 3 hours
