It takes 40 minutes more going up or 40/60 = 0.67 hours
more.
Let us say that:
t = the time required for him running down
t + 0.67 = time required for him running up
Since the distance of running up and down must be equal
therefore:
(3 miles / hr) * (t + 0.67) = (5 miles / h) * t
3 t + 2.01 = 5 t
2 t = 2.01
t = 1.005 hr
So the total length of the hike is:
length = 2 * (5 miles / hr) * (1.005 hr)
<span>length = 10.05 miles</span>
90 would be the largest then 59,48, -56, -80, and leaving -84 to be the smallest
You have to try. You can do this.

Answer: 2929 π inch
Step-by-step explanation:
Circumference is given by= 2πr
Here r= 1010 inches
So Tip of minute hand moves= 2π (1010inch)
= 2020 π inch for an hour
Now it comes from 12 to 33 o'clock= 1.45 hour so,
Tip of minute hand moves= 2020 π inch x 1.45
Tip of minute hand moves= 2929 π inch
