Since you already answered 'a' and 'b', then 'c' is easy. You know how far behind Aston was when his father crossed the finish line. So that's exactly the head start he needs, in order for them to tie at the finish.
The answer is 4.7 x 10^-4 If you move the decimal to the right, the exponent will be negative. If you move it to the left, the exponent will be positive.
Ok so TIME= distance/ speed So u divide now 2 by 3 = 0.66 So 0.66 HOURS you have to change it to minutes so u multiply by 60 which is 39.6 minutes. I wish it was helpful
