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
The total annual returns on each of the following investments would be 65 times 11,300 and the answer you’ll get divide by 2
There are 80 children. 45 of them are girls. The amount of boys is equal to:
That means there are 45 girls and 35 boys.
The ratio of boys to girls is: 
Simplify:
Your answer is 7:9
That decimal would be: 32% = 0.32
So, your answer is 0.32
Hope it helped.
62 + x = 82
Subtract both sides by 62.
x = 20.
