Delta drives at an average speed of 17 mph through traffic. What is her speed in kilometers per hour if 1 km is approximately equal to 0.62 miles round to the nearest 10th of a kilometer.

Answer 1

To convert Delta's speed from miles per hour (mph) to kilometers per hour (kph), you can use the conversion factor that 1 mile is approximately equal to 1.60934 kilometers.

Given that Delta's average speed is 17 mph, we can convert this speed to kilometers per hour using the following formula:

\[ \text{kph} = \text{mph} \times 1.60934 \]

Now, substituting in the values:

\[ \text{kph} = 17 , \text{mph} \times 1.60934 , \text{km/mile} \]

Calculating this gives:

\[ \text{kph} = 17 \times 1.60934 \approx 27.35878 \]

Now, rounding this to the nearest tenth of a kilometer:

\[ 27.35878 \approx 27.4 , \text{kph} \]

Therefore, Delta's speed in kilometers per hour is approximately 27.4 kph.
