Simple, take 3 1/2 turn it into a decimal which = 3.50 since
1/2 = 0.5 because 1 divide by 2 = 0.5
Same thing for 1 1/4 = 1.25 since
1/4 = 0.25 because 1 divide by 4 = 0.25
3.50 divide by 1.25 = 2.8 miles one hour.
You have to do 21+8+11=40. So 40 is the answer. Hope this helps.
To get a close estimate, we can round 49 up to 50 and 311 down to 300, obtaining an estimate of 50/300 = 1/6, or 0.1666... as a repeating decimal. That decimal approximation is a little less than one hundredth away from the actual decimal approximation of ≈ 0.1576
