Differentiate N w.r.t x
Q=21
Solution is given by
Using partial integration
The length of the trip at a distance of 300 miles and the given times are
- 6 hours
- 30/7 hours
- 300/x hours
- 300/x + 10 hours
- 300/x - 5 hours
<h3>How to determine the length of the trip?</h3>
The distance is given as:
d = 300
The formula is represented as:
d = r * t
Make t the subject
t = d/r
Substitute 300 for d
t = 300/r
When r = 50 mph,
t = 300/50
Evaluate
t = 60
When r= 70 mph, we have
t = 300/70
Evaluate
t = 30/7
When r = x, we have
t = 300/x
When r = x + 10, we have
t = 300/x + 10
When r = x - 5, we have
t = 300/x - 5

A train traveled 300 miles. How long did the trip take if the train was traveling at a rate of:
Note * Use the d=rt formula (distance = rate * time). NOTE: You may not be able to solve for the variable. If you do not have enough information to solve for the variable then write the equation.

195 candies are not cherry flavored. Since 15% are cherry flavored then 85% would not be. 85% of 230 is 195.5, however, there are no halves in a candy so it would be 195 candies.
The ratio/proportion is young / old = young / old.
We know that one ratio is 3 / 5, so we need to complete the other.
3 / 5 = young / 40
5 goes into 40, 8 times, therefore we need to multiply the numerator by 8 also.
3 x 8 = 24
