Answer:</h3>
157/34 ≈ 4.61764705882....∞
<h3>
Step-by-step explanation:</h3>
0,34 × n + 3.43 = 5
0,34n = 5 - 3.43
0,34n = 1,57
n = 157/2 ÷ 1/17
n = 157/34 ≈ 4.61764705882....∞
Answer:
I think its 24.86 mph
Step-by-step explanation:
n= speed of train
3*58=174 distance car traveled in 3 hours and train traveled in 7 hours
