Answer:
Korl will catch up to Krystal in 2 hours.
Step-by-step explanation:
18x3=54 this shows how long Krystal has driven in 3 hours.
27x2=54 this shows that in 2 hours Korl will have driven 5 mph.
Now as you can see both quotient are 54 and the question is How long until Korl catches up to Krystal so it's 2 hours

P = -23 + 0.13y
For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5
For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29
For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5
For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft

Calculate the spray interval to spray 5 times a day
----------------------------------------------------------------------
one day = 24 hour
24 ÷ 5 = 4.8 hours
----------------------------------------------------------------------
Find the interval in minutes
----------------------------------------------------------------------
4.8 hours = 4h 48 mins
4.8 hours = (4 x 60) + 48
4.8 hours =288 mins
----------------------------------------------------------------------
Answer: 288 mins
