:
Find the speeds in yd/sec
100/20 = 5 yd/sec
100/15 = 6.67 yd/sec
:
Write a distance equation; dist = speed * time
:
When the back tackles the t.e, the back will travel 5 yds more than t.E
6.67t = 5t + 5
6.67t - 5t = 5
1.67t = 5
t = 5/1.67
t = 3 sec
Find how many yds the back travels in 3 sec
3 * 6.67 = 20 yds
therefore
15 + 20 = 35 yd line, the back tackles the t.e
