Question

As mercury revolves around the sun it travels at a rate of approximately 30mi per second. Convert this rate to km per sec. At this rate how many km will mercury travel in 20 sec? In computations assume 1 mi equals 1.6 km. Do not round your answers

Answer 1

By converting the rate of Mercury's orbit around the sun from miles to kilometers using the given conversion factor and then multiplying this rate by the time in seconds, we find that Mercury travels 960 kilometers in 20 seconds.

Step-by-step explanation:

To convert the rate at which Mercury travels around the sun from miles per second to kilometers per second, use the given conversion factor: 1 mile = 1.6 kilometers.

Therefore, if Mercury travels at approximately 30 miles per second, you would multiply this value by 1.6 to find the speed in kilometers per second: 30 miles per second × 1.6 kilometers/mile

= 48 kilometers per second.

To calculate how many kilometers Mercury will travel in 20 seconds at this rate, you multiply the rate (48 km/sec) by the time (20 sec):

48 kilometers per second × 20 seconds = 960 kilometers.

Hence, Mercury will travel 960 kilometers in 20 seconds at the given rate.
