hile the other traves a 70miles per hout. How long will it take for the two trains to meet?___ hours Do not do any rounding
1 answer:
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
