Question

7.) The distance between two cities is described as 260 kilometers. What is the distance in miles? Make an estimate first, explain your reasoning briefly. Then calculate your answer using the fact that 1 inch equals 2.54 cm. Remember to round your answer appropriately: The way you write your answers should reflect its accuracy. Your answer should not be reported more accurately than your starting data.

Answer 1

Given that the distance between the two cities is 260 km,

and we know that

100,000 cm = 1km

Hence 260km = 260 * 100000

= 26,000,000cm

1km is about 0.6 miles hence 260km will be about 156 miles

Recall that 1 km = 0.6213 miles

Hence

260 km = 260 * 0.6213

= 161.538 miles
