jimmy and his family are on their way to visit some family friends who live 780 miles away from them.based on the route they chose they expect to complete their trip in three days. the distances and average speeds for the first two days driven are shown below. first day 4 hours at an averge speed of 60 miles per hour second day 6 hours at average speed of 65 miles per hour if the average speed on the third day is 60 miles pe hour how many more hours willit tak foe them to reach their family friends home
Answers
If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.
4 hours at 60 miles per hour = 4*60 = 240 miles
6 hours at 65 miles per hour = 6*65 = 390 miles
This is a total of 630 miles. There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

The fraction number 77/6 in the form of a mixed fraction number will be 12 ⁵/₆.
What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The fraction number is given below.
⇒ 77 / 6
Convert the fraction number into a mixed fraction number. Then we have
⇒ 77 / 6
⇒ 12 + 5/ 6
⇒ 12 ⁵/₆
The fraction number 77/6 in the form of a mixed fraction number will be 12 ⁵/₆.

Answer:
12
Step-by-step explanation:
= 12 remainder 5
The remainder of 5 forms the numerator of the fractional part of the mixed number while the denominator remains as 6
= 12
← mixed number

If so, just divide 7 by 21:
7 ÷ 21 = 0.3333333... (repeating decimal) or 1/3 as a fraction.
It means that one lap took 1/3 of a minute (20 seconds).

The number of steps it takes you to get to the remainder and quotient depends on how good your estimates are. For instance in the above diagram. You can see two different approaches of dividing 986 by 26 using partial quotients.
In the second approach in which there are fewer steps, We estimated that there are about 35 [26s] in 986. The 35 is our first partial quotient. We then multiply
Next we subtract
We again estimated that there are at least 2 [26s] in 76. The 2 is our second partial quotient.
We then multiply again,
Next, we subtract,
Now there are no 26s in 24. Hence 24 is the remainder.

Answer:
Upstream 1.1 hours and down stream 0.6875 hours.
Step-by-step explanation:
Jen motorboat travels at a speed of 13 mph in still water.
Now, the speed of river flows is 3 mph.
Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.
Therefore, to travel 11 miles upstream Jen will take hours.
And to travel 11 miles down stream Jen will take hours. (Answer)
