The metric measures equivalent to 65 mph are 104 km/h and 105.7 km/h.

Solución

The conversion factor between miles per hour and kilometers per hour is about 1.609. To convert 65 mph to km/h, multiply:   65 mph × 1.609 ≈ 104.6 km/h Now looking at the options: • 97.5 km per hour – This is too low. • 104 km per hour – This is very close to 104.6 km/h. • 105.7 km per hour – This is also close (105.7 km/h converts back to roughly 65.7 mph), so it’s acceptable if rounding is allowed. • 120.3 km per hour – This is much too high. Thus, the metric speeds that are equivalent (by reasonable rounding) to 65 mph are 104 km/h and 105.7 km/h.

Bonus Knowledge

Did you know that speed limits can vary greatly around the world? In many countries, the speed limit on highways is typically around 100-130 km/h. In fact, the excitement of hitting those speeds is often balanced with strict enforcement, as safety is a top priority in traffic regulations! When converting miles per hour to kilometers per hour, remember that 1 mile is approximately 1.60934 kilometers. So, when you're checking those speed limits, just multiply the mph value by 1.60934 to get a clear sense of how fast you can go in countries that measure speed in kilometers. For 65 mph, that's about 104.6 km/h!
