A biker can ride a bicycle 18 miles in 3 hours. the messenger estimates that it will take 7 hours to bike 22 miles. here is the messengers work:
step 1: 22-18=4
step 2: 3+4=7
what mistake did the messenger make?
β’ the messenger did not make a mistake. the estimate is correct
β’ the 3 and 4 should have been multiplied instead of added.
β’ the messenger used addition and Subtraction instead of multiplication and division
β’ the 22 and 18 should have been divided instead of subtracted
β’ the 22 and 18 should have been averaged instead of subtracted
