How long would it take to drive around earth's equator? (earth's circumference ≈ 40,000 km if driving at 143km?
Answered by admin @
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)
