a bike loop is 8 miles long. is ride around the loop 18 times. he used compensation to find out how far he rode. first he multiplied 20x8 =160. what should i do next?

Answer 1

you have calculated 8×20=160 miles
but you covered only 18 laps
so subtract 2×8=16 miles
Hence total distance covered=160-16=144 miles
