Question

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. How long will it take her to jog 6 miles.

Answer 1

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
