The steamer covered 145 km on the first day. on the second day by 63 km. more than on the first, and on the third day 80 km less than on the second. How many kilometers did the steamer sail on the third day?

1. Let us determine how many kilometers the motor ship passed in the second day, if this distance is 63 km longer than the distance in the first day:
145 + 63 = 208 km.
2. Determine how many kilometers the ship covered in the third day if it traveled 80 km less than in the second day:
208 – 80 = 128 km.
Answer: the motor ship covered 128 km in the third day.
