134 miles = ? inches 57. 8.9 x 105 tons = ? ounces 58. 1.35 kilometers per second = ? miles per hour

8490240 inches 29904000 ounces 3019.863 mph The 1st question is converting miles to inches. To do this simply multiply by 5280 (feet per mile) and then 12 (inches per foot). So 134 mi * 5280 ft/mi * 12 in/ft = 8490240 inches The 2nd question is converting tons to ounces. To do that multiply by 2000 (lb/ton), then 16 (ounces/lb). And of course, before that, calculate the actual number of tons with a simply multiplication. So 8.9 * 105 tons * 2000 lb/ton * 16 oz/lb = 29904000 ounces The 3rd question is converting km/sec to mi/h. So multiply by 0.621371 to convert to miles/sec, then multiply by 3600 to convert from seconds to hours. So 1.35 km/s * 0.621371 mi/km * 3600 s/h = 3019.863 mph
