Question

1. a samurai sword is about 29 inches in length. the distance from san bernardino to los angeles is 88 km. how many samurai swords would it take to equal this distance?

mass units length units volume units
1000 g = 1 kg 1000 m = 1 km 1000 ml = 1 l
1000 mg = 1 g 100 cm = 1 m 1 cm³ = 1 ml
1 lb = 454 g 1000 mm = 1 m 1 gal = 3.785 l
10 mm = 1 cm

Explanation:

Step1: Convert 88 km to inches

First, convert km to m. Since 1000 m = 1 km, then 88 km = 88×1000 m = 88000 m. Then convert m to inches. Since 1 m = 39.37 inches, so 88000 m = 88000×39.37 inches = 88000×39.37 = 3464560 inches.

Step2: Calculate the number of swords

Divide the total distance in inches by the length of one sword. Let \(n\) be the number of swords. Given the length of one sword is 29 inches. Then \(n=\frac{3464560}{29}\approx119467.59\). Since we need to count the number of whole - swords, we take the whole number part, and we need 119468 swords to cover the distance (rounding up because we need to fully cover the distance).

Answer:

119468
