M miles would have 1.6m kilometers. Number if kilometers in 5 miles is 8 kilometers.
Using the given conversion :
For m miles :
1 mile = 1.6 km
m miles = 1.6m
Hence, number of kilometers in m miles is : 1.6m
For 5 miles :
Number of kilometers = 1.6(5) = 8 kilometers
Hence, there are 8 kilometers in 5 miles .
