Answer:
12 miles in 4 hours is 3 mph
52-12=40 miles left
40 miles at 5 mph would take 8 hours
8+4=10
it took 10 hours to finish the trip.
Answer:
t=2.08 seconds.
Step-by-step explanation:
Well, in this example, H(t)=-0.6cos(2pi/2.5)t+1.5 should be equal to 1.2. If calculated, -0.6cos(0.8pi)t=1.2-1.5 which is equal to -0.6cos(0.8pi)t=-0.3, then cos(0.8pi)t=0.5. The value of cosine in terms of radians when it is equal to 0.5 is pi/3. So, cos(0.8pi)t=cos(pi/3). If simplified, (0.8pi)*t=5pi/3. pi's are cancelled out and t is calculated as 2.08333... If rounded to the nearest hundredth it is 2.08.
The correct answer is 200 .
So 2 weeks mean
250x 2= 500
Then .50 per mile so 500 miles mean
.50 x 500= 250
In total it will be
500+250= 750
