The correct answer is - the North Pole only.
During the Ice Age, or rather the glaciation, the continental glaciers originated from the North Pole and started expanding deeper into the continental masses from that starting point. The South Pole can be excluded because doesn't really matter if it is an Ice Age or not it is still frozen, plus Antarctica is surrounded with ocean waters thus the ice cannot expand further.
The glaciers during the Ice Age managed to occupy large portions of North America, coming as south as the northern part of what is now the United States. Also, the northern half of Europe and the northern half of Asia were also covered in ice.
Answer:
Energy is the ability to do work
Answer:
He travel for 2 h at the first part and 2 h for the second part.
Explanation:
given information:
business trip's distance, = 214 miles
v₁ = 53 mph
v₂ = 54 mph
t₁ = t
t₂ = 4 - t
now lets find the distance of each speed
s₁ = v₁ t₁ = 53 t₁
s₂ = v₂ t₂ = 54 t₂
= s₁ + s₂
214 = 53 t₁ + 54 t₂
214 = 53t + 54 (4-t)
214 = 53t + 216 - 54 t
t = 216 - 214
= 2 h
t₁ = t = 2 h
t₂ = 4 - t = 4 -2 = 2h
