Answer:
55mph
None of the option is correct
Step-by-step explanation:
Let v be the speed and t as the time taken. If speed varies inversely as the time it takes to drive, then v ∝ 1/t.
v = k/t where k is the constant of proportionality.
IF it takes Kris 5 hours when driving at 55 mph, then v = 55mph when t = 5 hours.
Substituting this values into the formula above;
55 = k/5
k = 55*5
k = 275mp/hr²
To calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t
v = 275/5
v = 55 mph
<em>Hence, martin will also need to drive at 55mph to take 5 hours</em>

Answer:
A Continental drift theory
Step-by-step explanation:
The continental drift theory was popularized by Alfred Wegener at the beginning of the past century (early 1900s). He stated that continents are land masses that float on magma, and they are continuously moving and drifting over the magma oceans that lie underneath. Wegener believed that all continents were once part of one single large continent called Pangea and that they started drifting away millions of years ago until they reached their current position. He also stated that the continents are still moving, but the movement is very slow and we can only notice it during earthquakes and tremors.
This theory has been updated and replaced by the study of plate tectonics.
