these are the round-trip distances that city buses traveled on different routes each month. calculate the total distance, in miles, that buses travel each route in one year.
350 3/5 miles to parkville
346 3/10 miles to green city
134 1/5 miles to evergreen town
327 4/5 miles to jefferson
413 7/10 miles to clinton city
first we add all the integers
350+346+134+327+413= 1572
first we add all the fractions altogether
⅗+3/10+⅕+⅘+7/10=3/5
the total distance is 1572 3/5

Can someone answer these problems for me
