The distance traveled is the circumference of the earth (around the equator). This distance is
d = 40,000 km

The average traveling speed is
V = 143 km/h
Note: Speed cannot have units of 143 km, as given in the question.

Because distance = Speed * time, therefore
time = distance/speed.

The time taken to travel around the equator is
time = (40,000 km)/(143 km/h)
= 279.7 hours

Answer: About 280 hours (nearest hour)
