Delta drives at an average speed of 17 miles per hour through traffic. What is her speed in kilometers per hour if 1 kilometer is approximately equal to 0.62 miles? Round to the nearest tenth of a kilometer.

Question

A. 10.5
B. 2.7
C. 27.4
D. 17.6

Answer 1

To convert Delta's speed from miles per hour to kilometers per hour, we need to multiply her speed in miles per hour by the conversion factor of 0.62 miles/kilometer.

Speed in kilometers per hour = 17 miles/hour * 0.62 miles/kilometer = 10.54 kilometers/hour

Rounded to the nearest tenth of a kilometer, Delta's speed is approximately 10.5 kilometers/hour.

So, the answer is A. 10.5.
