If 1 mile is equal to 1.61 kilometers, how many kilometers are there in 50 miles
Alik [6]

kilometers and miles are units used to measure distance.

1 mile is equal to 1.61 km

so if 1 mile is equivalent to 1.61 km

then to see how many kilometers are there in 50 miles we have to multiply 50 miles by 1.61 km/mile

therefore the number of km in miles is - 50 miles x 1.61 km/mile = 80.5 km

distance in km - 80.5 km
