= 24.14016 km
Therefore, 15 miles is equal to 24.14016 km.
Example 2: The distance between Peter’s college to his house is 4 miles, how many kilometres does Peter cover from his college to home?
Solution:
To find: Distance travelled in kilometres.
Distance between college to house = 4 miles (given)
Using miles to km formula,
Distance travels in kilometres by Peter = (4 miles x 1.6)
= 6.4 (approx)
Answer: Peter travels approximately 6.4 kilometres from his college to home.
