Answer:
179 mph
Step-by-step explanation:
Given: Average speed to cover 19 lap is 159 mph
Now, finding the speed of driver in 20th lap to attain 160 mph as an average speed.
Average Speed =
Considering x as speed in 20th lap.
⇒ 160 =
⇒ 160 =
Now, multiplying both side by 20.
⇒ 160 =
⇒ 3200 =
∴ x = 179 mph
179 mph should be the speed of driver in his 20th lap to attain an average speed of 160 mph.
If the proportion of iris to roses in Nikki's garden is 2: 5, it means that for 25 roses: (2/5) = (10/25). Therefore to maintain the proportion by adding 20 roses: (2/5) = (18/45). The number of irises after the addition of roses will be 10 + 18 = 28 irises.
The speed is the ratio between the distance and the time:
Data:
d=6343miles
t=9h
Then, the plane traveled at a speed of 704.77 miles per hour.
