Answer:
An possible equation 50t (min) - 700 = 0
and t= 13, 4 min a result a little less than expected 13, 1/3 = 13, 33 min
Step-by-step explanation:
Only need to use rules of three or using rates
1 Km = 1000 m
[tex]40s * \frac{1 min}{60 s} = 0.67 min =
[tex]\frac{0.67 min}{50 m} = \frac{t}{1000m}[/tex]
t= \frac{0.67* 1000}{50} = 13,4 min
An possible equation 50t - 700 = 0
