QuestionIn England, people use mile per hour as a unit of speed on roads. In Egypt, we use kilometer per hour on roads. In physics class, students tried to compare the speeds indicated 20 MPH in these signs with the SI unit of speed. Which of students' attempts is correct?
A $-20 \mathrm{~km} / \mathrm{h}>20 \mathrm{MPH}>20 \mathrm{~m} / \mathrm{s}$ B- $20 \mathrm{MPH}>20 \mathrm{~km} / \mathrm{h}>20 \mathrm{~m} / \mathrm{s}$ C. $20 \mathrm{~m} / \mathrm{s}>20 \mathrm{~km} / \mathrm{h}>20 \mathrm{MPH}$
D- $20 \mathrm{~m} / \mathrm{s}>20 \mathrm{MPH}>20 \mathrm{~km} / \mathrm{h}$
