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

Answer:
1.55 kilograms.
Step-by-step explanation:
Given:
A farmer sells 6.2 kilograms of apples and pears at the farmer's market.
of this weight is apples, and the rest is pears.
Question asked:
How many kilograms of pears did she sell at the farmer's market?
Solution:
Total weight of apples and pears = 6.2 kilograms
<u>As </u><u> of this weight is apples </u>
Weight of apples =
Remaining weight ( pears ) = 6.2 - 4.65 = 1.55 kilograms
Weight of pears = 1.55 kilograms
Thus, she sell 1.55 kilograms of pears at the farmer's market.
the correct answer is -9
