From the first part of the condition, the distance is

2.4*55 = 132 miles.

From the second part,the time is

132%2F40 = 3.3 hours = 3 hours 18 minutes.

That's because you're using DIRECT variation. T+=+D%2FS, which means that time varies INVERSELY with speed. If you remember that, and 

work the problem out, you'll see that the distance is: 2.4 * 55, and that the time taken would be: %282.4%2855%29%29%2F40, or highlight_green%283.3%29 hours
