Answer:
Step-by-step explanation:
SOLUTION
At the same time t,
Train 1 would have covered a distance of 80t, since distance = average speed x time.
Train 2 would have covered a distance of 70t.
Now both added should give 210 miles
That is 80t + 70t = 210
150t = 210
t = 210/150
t = 1.4 hours
Answer: x= 3
Step-by-step explanation:
2x + 5 = 11
2x = 6
x = 3
Speed = distance / time
<span>Speed = 400 / 253 </span>
<span>Speed = 1.58 m/s approx</span>
