2.3hours he travel at 20km/hr
so distance covered = 2.3*20=46 km
rest 4.7 hours he travel at 30km/hr
so distance covered =4.7*30=141km
so total distance =46+141=187km
so distance covered = 2.3*20=46 km
rest 4.7 hours he travel at 30km/hr
so distance covered =4.7*30=141km
so total distance =46+141=187km
