Question

The circumference of the earth is 2.4x109 miles. if you traveled at an average of 8.5x10 miles per hour, how long would it take for you to go around the earth? round your answer to the nearest whole number.

a. 2,820 hours
c. 354 hours
b. 282 hours
d. 3,500 hours

Answer 1

282 hr <======= see below

Explanation:

Distance / rate = time

2.4 x 10^9 mi / 85 m/hr = 28235294 hr

You must have left the power of 10 off of your speed

probably should be 8.5 x 10^6 perhaps? then answer is 282

If speed was 8.5 x 10^5 then answer becomes ~ 2820
