Answer:
5 minutes
Step-by-step explanation:
To find the number of minutes it takes Jason to run a mile, we have to first find the rate at which he runs.
This is called Jason's speed. It is given as


From the formula of speed, time is given as:

Time taken for Jason to run 1 mile (1760 yards) will therefore be:

Converting this time to minutes yields:
60 seconds = 1 minute
300.34 equals:

It takes Jason 5 minutes to run 1 mile.

The diameter is 26
C = pi * d where d is the diameter
C = 3.14 *26
C =81.64 ft
Answer:
S = 13 - x
T = (18 + x) / 2
Step-by-step explanation:
S = 18
T= 18
Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.
S = 18 - x
T= 18 + x
Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.
S = 18 - x - 5
T = 18 + x / 2
Simplify 18-5.
S = 13 - x
T = (18 + x) / 2
