Answer:

72km/h

Step-by-step explanation:

Convert units to kilometers and hours.

275 seconds ÷ 60² ≈ 0.0764 hours

5500 meters ÷ 1000 = 5.5 km

Convert to kilometers/hour.

5.5km ÷ 0.0764hrs = 72km/h

\sqrt[4]{x^{7} }

this is the same concept basically as simplifying \sqrt{x} into x^{\frac{1}{2} }. You can see that the denominator is in front of the radical and that any numbers in the numerator are the power of the number underneath.

Ronch [10]

Answer:

75%
