Answer:
s = 71 mph, and s+9 = f = 80 mph
Step-by-step explanation:
The distances the two busses travel add up to 604 mi.
Letting f be the faster speed and s the slower. Then f = s + 9 (mph).
Then (s + 9)(mph)(4 hr) + (s)(mph)(4 hr) = 604 mi. Solve this for s:
4s + 36 + 4s = 604 mi, or 8s = 568. Finally, s = 71 mph, and s+9 = f = 80 mph.

<h3>Given:</h3>
▪ 
First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:

Divide the coefficient:

Divide the base by subtracting the exponents of the base 10.

Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.
