Final answer:
The distance traveled by the bus is 28m³n¹¹ kph × hour.
Step-by-step explanation:
To find the distance traveled by the bus, we can use the formula D = rt, where D is the distance, r is the rate, and t is the time. In this case, the rate of the bus is 7m²n⁵ kph and the time is 4mn⁶ hours. So, the distance traveled can be represented as:
D = (7m²n⁵) * (4mn⁶) = 28m³n¹¹ kph × hour
Therefore, the distance traveled by the bus is 28m³n¹¹ kph × hour.
