Answer:
x = 55
Step-by-step explanation:
Given that x varies inversely as y then the equation relating them is
x = ← k is the constant of variation
To find k use the condition x = 11 when y = 15
11= ( multiply both sides by 15 )
165 = k
x = ← equation of variation
When y = 3 , then
x = = 55
Answer: Ayshab's average speed for the whole journey =
Step-by-step explanation:
Formula: Speed =
i.e. Time =
If Ayshab walked x miles at 4 mph, then time taken by him = hours
If she then walked 2x miles at 3 mph, then time for this period = hours
Average speed =
Hence, Ayshab's average speed for the whole journey =
