On each 3 days, Derrick rode 6.45 km. to school, 150 meters to the library and 500 meters back home. How many kilometers did he ride all together?

Answer 1

Found this on studysoup;

Just add all 3 numbers up 6.45+ 0.15+0.5 =7.1 Since it was three days multiply the 7.1 by three =7.1x3 =24 So for three days derrick rode for 24 km Hoped I helped :)


Hope that helps!

Answer 2

Total Distance = 6.45km + 150m + 500m

Convert meters to kilometers:
Total Distance = 6.45km + 0.15km + 0.5km

Add them up:
Total Distance = 7.1km

Find total distance he rode in 3 days:
1 day = 7.1 km
3 days = 7.1 x 3 = 21.3 km

Answer: He rode 21.3 km in the 3 days.
