To calculate the distance traveled by the Japanese JR-Maglev Train in 1.5 hours at an average speed of 603 km/h, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Given that the speed is 603 km/h and the time is 1.5 hours, you can plug in the values:
\[ \text{Distance} = 603 , \text{km/h} \times 1.5 , \text{h} \]
Calculating that:
\[ \text{Distance} = 603 \times 1.5 = 904.5 , \text{km} \]
Therefore, the JR-Maglev Train can travel 904.5 kilometers in 1.5 hours.
