Rahul travels 30km/h for 20 minutes and then 20km/h for 10 minutes on his motorcycle. What will be the total distance he travels in 30 minutes
Answers
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
