Question

as the earth revolves around the sun, it travels at a rate of approximately 18 miles per second. convert this rate to kilometers per second. at this rate, how many kilometers will the earth travel in 15 seconds? in your computations, assume that 1 mile is equal to 1.6 kilometers. do not round your answers.
rate: (\frac{\text{km}}{\text{s}})
distance traveled in 15 seconds: (\text{km})

Explanation:

Step1: Convert miles to km

$18 \text{ miles/sec} \times 1.6 \text{ km/mile} = 28.8 \text{ km/sec}$

Step2: Calculate distance in 15 sec

$28.8 \text{ km/sec} \times 15 \text{ sec} = 432 \text{ km}$

Answer:

Rate: $28.8$ $\frac{\text{km}}{\text{s}}$
Distance traveled in 15 seconds: $432$ km
