Step-by-step explanation:
We want to find the tricycle's speed in kilometers per hour.
Therefore, we must divide the kilometers traveled by the number of hours.
speed= kilometers / hours
The tricycle travels 180 kilometers in 4 hours.
speed= 180 km / 4 hrs
Divide 180 km by 4 hrs.
⇒ 180/4=45
speed= 45 km / hour
The tricycle's speed is 45 kilometers per hour.
