Question

A car travel 180 km in 5 hours. Time required for the car to cover 30 km with the same speed = ?​

Answer 1

Answer:

50 min

Step-by-step explanation

Distance=180km

Time= 5hrs

Speed=180/5=36km/hr

now, 36 km in = 1hr

therefore, 30km in=$\frac{1}{36} *30$=5/6 hr

in min = 5/6 *60=50 min

Answer 2

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
