Mark has to take 15ml of medicine twice per day for 7 days. How much medicine does he need?
Correct Answer
D. 210ml
Explanation
Mark needs to take 15ml of medicine twice per day for 7 days. To find out how much medicine he needs in total, we need to multiply the amount of medicine he takes per day (15ml) by the number of times he takes it per day (2) and then multiply that by the number of days he takes it (7). So, 15ml x 2 x 7 = 210ml. Therefore, Mark needs 210ml of medicine in total.

Bernard is running from Land’s End to John O’ Groats. The distance is 874 miles. If he runs 25 miles a day, how many days will it take him to run the distance?
Correct Answer
D. 35
Explanation
Bernard is running a distance of 874 miles from Land's End to John O' Groats. If he runs 25 miles a day, we can calculate the number of days it will take him to complete the distance by dividing the total distance by the distance he runs each day. Therefore, 874 miles divided by 25 miles/day equals 34.96 days. Since we cannot have a fraction of a day, we round up to the nearest whole number, which is 35. Therefore, it will take Bernard 35 days to run the entire distance.
