Jess jogs at a rate of 6 mph. The next time she jogs, she increases her speed to a rate of 7 mph. How long will it take her to jog 6 miles?
6 mi / 7 mph = ? h
i got about 51 mins. is that right>
To find out how long it will take Jess to jog 6 miles, we can use the formula for time:
Time = Distance / Speed
First, let's calculate the time it takes for Jess to jog 6 miles at a rate of 6 mph:
Time1 = Distance / Speed1
= 6 miles / 6 mph
= 1 hour
Therefore, it takes Jess 1 hour to jog 6 miles at a rate of 6 mph.
Now, let's calculate the time it takes for Jess to jog 6 miles at a rate of 7 mph:
Time2 = Distance / Speed2
= 6 miles / 7 mph
≈ 0.857 hours
Therefore, it will take Jess approximately 0.857 hours (or approximately 51.4 minutes) to jog 6 miles at a rate of 7 mph.
