Step-by-Step Solution:
Step 1 of 3

Solution 51E: Unit conversion (a) 5.00 days to s, Here, we have to convert day to s, by using some of the conversion factors. We know 1 day = 24 h 1 h = 60 min 1 min = 60 s Thus the conversion factors are 24 h ,60 min, 60 s 1 day 1 h 1 min Thus, 5 days = 5 days x 1 dayx 61 hinx 1 min = 432000 s 5 = 4.32 x 10 s 5 Therefore, 5 days is equal to 4.32 x 10 s (b) 0.0550 mi to m Here, we have to convert mi to m, by using some of the conversion factors. We know 1 mi = 1.6093 km 1 km =1000 m Thus the conversion factors are 1.61 mikm, 11 kmm Thus, 1.6093 km 1000 m 0.0550 mi = 0.0550 mi x 1 mi x 1 km = 88.51 m Therefore, 0.0550 mi is equal to 88.51 m (c) \$1 89/gal to dollars per liter Here, we have to convert \$/gal to \$/L, by using some of the conversion factors. We know 1 gal = 4 qt 1 qt =1.057 L Thus the conversion factors are 1 gal, 1 qt 4 qt 1.057 L Thus, dollar 1 gal 1 qt \$1 89/gal = 189 gal x 4 qtx 1.057 L = 44.7 dollar/L Therefore, \$1 89/gal is equal to 44.7 dollar/L (d) 0.510 in./ms to km/hr Here, we have to convert 0.510 in./ms to km/hr, by using some of the conversion factors. We know 1 in = 2.54 cm 1000 m = 1km 1 m= 100 cm 1 ms =...
