look at the units. You want to convert speed to time. So, speed already relates distance to time: m/s
But you want to end up with sec, not m, so divide meters by meters/sec to end up with sec.
m / (m/s) = m * s/m = s
They've only given you two pieces of data, so work with them:
227m / (490m/s) = 227 / 490 s = 0.46 s
A jet travels at 490 m/s.
How long does it take to travel 227m?
Answer in units of s
