Answer:
x = 4 4/5 minutes
Step-by-step explanation:
We can proportions to solve. Put distance over time
1/6 miles 1 miles
------------------ = -------------------
4/5 minutes x minutes
Using cross products
1/6 * x = 4/5 *1
1/6x = 4/5
Multiply by 6 on each side to get x alone
1/6 * 6 x = 6*4/5
x = 24/5
Changing this to a mixed number
x = 4 4/5 minutes
