on each of 3 days Derrick rode 6.45 km to school 150 meters to the library and then 500 meters back home. how many kilometers did he ride for the 3 days total?
1,969.35. first you add them all up (6.45+150+500)=656.45, which is how much he rode in 1 day, no you multiply it by 3. so 3(656.45)=1,969.35 so thats how many km he rode in three days
