Answer:
336
Step-by-step explanation:
26' wheel @ 90 rpms = 2,340 inches / min (26 x 90)
2,340 inches / min = 140,400 inches / hour (2,340 x 60)
140,400 inches / hour = 11,700 feet / hour (140,400 / 12)
11,700 feet / hour = approx. 2.216 miles / hour (11,700 / 5,280)
Let x be the number that Xavier is thinking of.
Now let's "translate" the words into an equation:
9 + 4x = 2x - 15
This simplifies to 2x = -24, which gives x = -12.
