slavikrds [6]

Answer: The speed is equivalent to 159.39 kilometers per hour or 2.65 kilometers per minute.

Explanation:

Given, The speed of a race car = 99 miles/ hour

To convert the speed into kilometers per hour and kilometers per minute

So, Speed of car = (99 ) x (1.61 )

= 159.39 kilometers per hour.

Also, 1 hour = 60 minutes

Then, Speed of car = (159.39) ÷60

= 2.6565≈2.65 kilometer per minute.

Hence, the speed is equivalent to 159.39 kilometers per hour or 2.65 kilometers per minute.
