A speed of limit of 100 kilometers per hour is approximately equal to 62 miles per hour predict the following measures round you r answers to the nearest whole number a. a speed limit in mph for a speed limit of 75 kph
b. a speed limit in kph for a speed limit of 20 mph
2 answers:
Answer:
a. 46.5 mph
b. 32.3 kph
Step-by-step explanation:
If the speed limit is 100 km/hour we and this equals 62 mile per hour we can determine how many kilometers is in miles and vice versa:
WE can do this as:
Therefore the 0.62 miles per kilometer
a) For 75 kph we can use the conversion we determine to convert to miles per hour:
It takes a speed limit of 46.5 mph for a 75 kph limit
b) For 20 mph we can use the conversion we determine to convert to kilometers per hour:
It takes a speed limit of 32.3 kph for a 20 mph limit
47mph and 32 kph The ratio is 1.6kph for every 1mph so for the first one you divide by 1.6 and the second you multiply
