A parcel is carried along two conveyor belts, one straight after the other. The parcel does not stop at any point.
| Belt | Distance travelled | Constant speed |
|---|---|---|
| First | 60 m | 1.00 m/s |
| Second | 90 m | not known |
The average speed of the parcel over both belts is 1.50 m/s.
What is the speed of the parcel on the second belt?
