Explanation for Question 37 From the Math (Calc) Section on the 2018 March Sat
Question 37 says during the fourth split of the race, 2 the teen rode at a rate of 28 strokes per minute to the nearest 3 whole number. How many strokes did it take the team to complete the final 4 500 meters of the race? 5 So the first thing we know is that if we go to this part 6 of the table, this the last 500 meters of the race, 7 this last bottom row, we can see that it took 108 seconds for 8 the team to complete this section. So 108 section seconds. 9 And we know that it w that, uh, the team rose at a rate 10 of 28 strokes per minutes. So we know we have to convert this into 11 minutes and I'm going to do that by divided by 60. 12 And that tells me that it took the team 1.8 minutes to row the 13 last 500 meters. Now, 14 since this team can row at a rate of 28 strokes per minute, 15 to find the number of strokes that they wrote during that time period, 16 I'm just going to multiply this by 28. And that gives me 50.4, 17 that the question asks us to round to the nearest whole number. 18 Doesn't tell us round up or down. It says to the nearest whole number 19 and that nearest whole number is 50. 20 So that means that the answer to this question is before.
