What is 1/3 as a slope?
The answer is approximately 18.43º. A slope of 1 in 3 means the slope is 1/3. It also means a rise of 1 and a run of 3. On a graph, starting at the origin, go up 1 unit, then from there, go to the right 3 units.

He will run 20miles for 10 minutes
Rate = Distance / time
for the first jog
distance = 8 miles
time = 4 minutes
rate = 8 / 4
rate = 2 miles/minutes
to calculate the distance covered in 10 minutes
from Rate = distance / time
Introducing cross multiplication
Distance = rate x time
Distance = 2 x 10
Distance = 20miles
