Train X and train Y pass one another traveling in opposite directions. Twenty minutes later they are 100 miles apart. If train X’s constant speed is 30 miles per hour greater than train Y’s, how far does train X travel during that time? | [
"72",
"55",

THe question seems incorrect. it should not be 80% at the speed of 80. However if it's 20% at the speed of 80, Answer comes out 55.
The question is correct. Here's the explanation:
Let distance be D. We can find the total timeequate it, which comes as:
0.8D / 80 + 0.2D / v = D / 55 => v = 50 (Option C). | AquaRat_train |

"60%",
"28%",
"33.33%",
"25%"
] | D | Lats year: budget = $100, price = $1 --> the number of computers purchased = 100/1 = 100;
This year: budget = $150, price = $1.2 --> the number of computers purchased = 150/1.2 = 125.
Increase in the number of computers purchased = 25%.
