Cities A, B, C, D, and E are located on a straight road as shown in the figure, and the distance between cities A and E is 300 kilometers.
Ela, driving her vehicle, started moving from city A at a constant speed of 90 kilometers per hour and will go to city E using this road without taking a break. Her mother asked Ela to share her live location throughout the journey and occasionally checked this sharing to write down in the table below how many minutes after Ela left city A she was at which point.
| Elapsed time | Current location |
| After 10 minutes | Exactly midway between cities A and B |
| After 40 minutes | Exactly midway between cities B and C |
| After 140 minutes | Exactly midway between cities D and E |
According to this, what is the distance between cities C and D in kilometers?
A) 30 B) 35 C) 40 D) 45 E) 50
