Question

You drive your car, 630 miles in 10.6 hours. What was your average speed in miles per hour? Kilometers per second ? (1.609km = 1mile)

Answer 1

Step-by-step explanation:

To find the average speed, we can use the formula:

Average speed = Total distance / Total time

Total distance = 630 miles

Total time = 10.6 hours

So the average speed is:

Average speed = 630 miles / 10.6 hours

= 59.43 miles per hour

To convert miles per hour to kilometers per second, we can use the following conversions:

1 mile = 1.609 kilometers

1 hour = 3600 seconds

So, to convert 59.43 miles per hour to kilometers per second, we can do the following:

59.43 miles/hour * 1.609 kilometers/mile * 1/3600 hour/second = 0.0265 kilometers/second

Therefore, the average speed in kilometers per second is approximately 0.0265 kilometers per second.
