Answer:
100 miles
Step-by-step explanation:
We know this because,
lets say they start at 0
0+the first 15 is 15
15+23=38
then when they backtrack 2 miles
you subtract 2
38-2=36
so they have gone 36 miles so far.
to get the amount of miles they have to go you can subtract.
136-36=100
So that is how I got 100.

Answer:
1 hour
Step-by-step explanation:
The time it takes to travel to a destination varies inversely as its speed
T= k/S
K= TS
Time= 2 hours
Speed= 40mph
K= 2×40
= 80
Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows
T= 80/80
= 1 hour
Hence the new travel time is 1 hour
Answer:
First mechanic worked for 10 hours and second mechanic worked for 15 hours.
Step-by-step explanation:
Let first mechanic worked for X hours and second mechanic worked for Y hours .
Now, according to the question , they worked for a total of 25 hours .
Thus ,
X + Y = 25.
Y = 25 - X -(1)
Also, first mechanic is charging $ 95 per hour and second mechanic is charging $115 per hour .
Thus, total money charged by them will be 95X + 115Y .
Which is given to be $2675 in the question.
Thus 95X + 115Y = 2675. -(2)
Putting equation 1 in equation 2 we get ,
95X + 2875 - 115X = 2675
20X = 200
X = 10 hours.
Thus , Y = 25 - X = 15 hours.
Thus first mechanic worked for 10 hours and second mechanic worked for 15 hours.
