To find the total distance traveled, we need to calculate the distance traveled at each speed and then add them together.

Distance traveled at 45 km/h for 3 hours:

Distance = Speed x Time

Distance = 45 km/h x 3 hrs

Distance = 135 km

Distance traveled at 35 km/h for 2 hours:

Distance = Speed x Time

Distance = 35 km/h x 2 hrs

Distance = 70 km

Total distance traveled:

Total distance = 135 km + 70 km

Total distance = 205 km

To find the average speed, we need to calculate the total distance traveled and divide it by the total time taken.

Total time taken:

Total time = 3 hrs + 2 hrs

Total time = 5 hrs

Average speed:

Average speed = Total distance / Total time

Average speed = 205 km / 5 hrs

Average speed = 41 km/h

Therefore, the total distance traveled by the man is 205 km and his average speed is 41 km/h.
