Quizplus · Accepted Answer

First, we need to convert meters per second to kilometers per hour by multiplying by 3.6 (since 1 hour = 3600 seconds):
111 m/s x 3.6 = 400.8 km/h

Next, we need to convert kilometers per hour to miles per hour by dividing by 1.61:
400.8 km/h ÷ 1.61 = 248.45 mi/h

Rounding to the nearest whole number gives us 248 mi/h, which is choice C.
