Answer:
The value of y is 9.
Step-by-step explanation:
Given : W be a point between points U and V also, UV = 13, UW = 2y – 9, and WV = y – 5
We have to solve for y.
Since, W is a point between points U and V .
Then distance of point W from U and distance of point from V is equal to the distance of UV.
Then, UW + WV = UV
Substitute , the values, we get,
Then 2y – 9 + y – 5 = 13
Solving for y , we get,
⇒ 3y - 14 = 13
⇒ 3y = 13 + 14
⇒ 3y = 27
⇒ y = 9
Thus, the value of y is 9.
Answer: The jet's speed from A to B would be 5.5 km/hr.
Step-by-step explanation:
Since we have given that
Distance = 2500 meter
Outbound speed be x
Average speed be
Time = 9 hours 10 minutes =
According to question, it becomes,
Hence, the jet's speed from A to B would be 5.5 km/hr.
a. 7/11
b. 5/12
c. 3/20
d. 5/13
