Daima

Answer:

at 6.00 p.m. it will overtake and distance will be 6 X40 = 240km/h from the depot

Step-by-step explanation:

Earlier truck is  2 X 30 = 60km/h away from the depot by the time the second truck starts  40km/ h

Net speed of second truck = 40-30 = 10km/ hour

Distance = 60km

Time = Distance / speed = 60/10 = 6 hours
