C. The y-intercept represents how far away she is at time = 0, meaning before she started traveling home. Therefore it must be a single value rather than a per-minute rate, and it must be measured in miles since it's a measure of distance. C is the only answer that fits.

1 stone =14 pounds ⇒ 1 pound= 1/14 stone

42 kg= 42*2.2 pounds= 92.4 pounds  

92.4 pounds = 92.4 * 1/14 stone= 6.6 stones
