(trigonometry) plz me on this problem

1) In 365 days, Earth makes = 360 degree
So, In 1 day, It would be: 360/365 = 0.986 degree

2) We know, Ф / 360 * 2πr
0.986/360 * 2 * 3.14 * 93
1 / 365.11  * 584.04
Approx. 1.60 million miles

In short, Your Answer would be 1.60 million miles

3) We know, speed = Distance / Time
Here, distance = 1.60 million miles
Time = 24 hour

Substitute their values, 
s = 1.60 / 24
s = 0.067 × 1,000,000
s = 66666.67

In short, Your Answer would be  66666.67 mph

Hope this helps!
