Answer:
1.4 times k
Explanation:
If k feet is the distance from home plate to third base, and the distance from first base to third base is 1.4 times the previous value, then
distance from first base to third base = 1.4 * k or 1.4 times k
If, for example, k=90 feet, then from first to third base there are
1.4*90=126 feet
