Final answer:
To convert 40 km/h to miles per hour, multiply by the approximate conversion factor of 0.621, which yields about 24.84 mi/h.
Step-by-step explanation:
If the speed limit is 40 km/h in British Columbia and Ron wants to know what that is approximately in miles per hour (mi/h), he can use the rough conversion factor that 1 km is approximately equal to 0.621 miles. Therefore, to convert the speed limit to miles per hour, he can multiply the km/h value by this conversion factor.
Converting Kilometers per Hour to Miles per Hour
To find out how many miles per hour is 40 km/h:
40 km/h * 0.621 = 24.84 mi/h (approximately)
So if the speed limit is 40 km/h, it would be approximately 24.84 miles per hour.
