Question

Sebastian drove for 2.2 hours at an average rate of 43.5 miles per hour. He calculates that he drove 95.7 miles. He knows the answer should be near 80, because 40 times 2 is 80. Which best explains Sebastian’s actual solution?

A.The actual product is reasonable because it is near 80 but greater than 80. Both factors were rounded down, making the estimate lower than the actual product.

B.The actual product is unreasonable. It should be near 80 but less than 80 because both factors were rounded down.

C.The actual product is reasonable because the estimate and actual answers both have two places to the left of the decimal.

D.The actual product is unreasonable because the estimate has zero places to the right of the decimal and the actual product has one decimal place to the right of the decimal.

Answer 1

A

Explanation:

43.5 x 2.2 will give his actual distance

take 43.5 as 435/10 and 2.2 as 22/10

435x22 = 8700+870=9570

10x10=100

ans= 9570/100

=95.7.

Because Seb rounded DOWN all the values, making it 40x2=80, which is wrong

Answer 2

`(10)/(17)`and divides by 10
