Question

Select the expression that represents this real-world situation.

Vesi snowboards 4 hours before lunch and 3 hours after lunch each day. How many hours did she snowboard in 2 days?

4 + 3 + 2
(4 + 3) x 2
4 x 3 ÷ 2
(4 x 3) − 2

Answer 1

(4+3)x2

4 is before lunch and you have to add it to after lunch to get how long she snowboards in one day.
If she snowboards two days you have to multiple that by two to keep it directly proportional.

Answer 2

Answer:(4 + 3) x 2

Explanation:

Vesi snowboards 4 hours before lunch and 3 hours after lunch each day, so the total time she spends snowboarding each day is:

4 + 3 = 7 hours

The question is asking how many hours Vesi snowboarded in 2 days, so we need to multiply the daily total by 2:

7 x 2 = 14

Therefore, the expression that represents this real-world situation is:

B. (4 + 3) x 2 = 14.

Option A adds 2 hours which is not correct as Vesi snowboards 7 hours each day, not 2 hours. Option C multiplies and divides, which is not necessary in this case. Option D multiplies and subtracts, which is also not correct.
