Answer:
proportional/equal
Step-by-step explanation:
doesnt need
40 km - meters is 40 * 1000 whch is 40000 meters per hour
4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15). The trick here is to combine the exponents.
Another way to write this problem would be:
4*d^18
---------- . Here d^18 divided by d^3 results in d^15, so again the final
d^3 answer is 4*d^15.
