a speed of limit of 100 kilometers per hour is approximately equal to 62 miles per hour predict the following measures round your 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

Answer :

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

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:

[tex]62/100=0.62[/tex]

Therefore the 0.62 miles per kilometer

a) For 75 kph we can use the conversion we determine to convert to miles per hour:

[tex]75*0.62=46.5[/tex]

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:

[tex]20/0.62=32.3[/tex]

It takes a speed limit of 32.3 kph for a 20 mph limit
