Answer:
1,171,875
Step-by-step explanation:
The sequence is multiplying by 5 every time. It will be 3, 15, 75, 375, 1875, 9375, 46,875, 234,375, and then 1,171,875
Simplify ( 5 x 3-x+14)-(3 x 2-9 x + 4)= 5x3 - 3x2+8x+10
I think it would be 2 and a half hours/ 2 hours and 30 minutes.
62 miles 217/3.5 to get mph then mph is 62 so every hour they travel 62 miles
