case 1 : Rahul travels 30km/h for 20 min.

speed of Rahul = 30 km/h , time = 20min = 20/60 h = 1/3 h

we know, distance travelled = speed × time

= 30 km/h × 1/3 h = 10 km

case 2 : again, Rahul travels 20km/h for 10min.

speed of Rahul = 20 km/h , time = 10 min = 10/60 h = 1/6 h

so, distance travelled by Rahul in 2nd situation = 20km/h × 1/6 h = 10/3 km.

now total distance travelled by Rahul in 30 min = 10km + 10/3km = 40/3 km

so, distance travelled by Rahul in 2nd situation = 20km/h × 1/6 h = 10/3 km.

now total distance travelled by Rahul in 30 min = 10km + 10/3km = 40/3 km
