distance traveled = 3 + 2/5 = 3 +0.4 = 3.4 km
time = 1 hour
So, speed = distance/time = 3.4/1 = 3.4 km/hr
now, time = 2+1/2 = 5/2 hours
distance = speed×time
= 3.4×5/2 = 8.5 km or 8 and 1/2 km
time = 1 hour
So, speed = distance/time = 3.4/1 = 3.4 km/hr
now, time = 2+1/2 = 5/2 hours
distance = speed×time
= 3.4×5/2 = 8.5 km or 8 and 1/2 km
