Answer:
0.86 hour
Step-by-step explanation:
Jess jogs at a rate of 6 miles per hour.
The next time she jogs she increases her speed to a rate of 7 mile per hour.
The new rate of Jess's jogging is 7 miles per hour
How long will it take her to jog 6 miles?
Hence:
7 miles = 1 hour
6 miles = x hours
Cross Multiply
7 × x = 6 × 1
x = 6/7
x = 0.8571428571 hour
Approximately = 0.86 hour
It will take Jess 0.86 hour to jog for 6 miles
