1.a television advertisement claims 'because the earth is rotating at over 1000 miles per hour, you will travel over 650 million in a lifetime calculate, to the nearest year, the lenght of a lifetime SOLUTION The earth travel in a year = 1000 x 24 x 365 = 8760000 Length of a lifetime = 650000000 / 8760000 = 74 yr. (corr. to nearest yr.) 2.in the 1998 grand prix in australia, mika complete the fastest lap in a time of 1 minute 31.649 seconds. his average speed was 208.303 kilometres per hour for that lap calculate the length of the lap,to the nearest metre Average speed in m/s = (208.303 x 1000) / (60 x 60) = 57.862 m/s Length of the lap = 57.862 x (60 + 31.649) = 5302.9 m = 5303 m (corr. to nearest m)
