1 mile = 1610 m
1 h = 60*60 = 3600 s
1 mi/h = 1610/3600 = 0.44704 m/s
60 mi/h = 60*0.44704 = 26.8224 m/s
if we changed our speed limit signs to metric what would probably replace 60 mi/h
1.If we changed our speed limit signs to metric, what would probably replace the following? (Enter your answers to the nearest km/h.) (a) 15 mi/h km/h (b) 80 mi/h km/h 2.A quantity of water is poured into a graduated cylinder, which then reads 154 mL. What is the mass of the water in kilograms?
The speed limit on U.S. highways is 65 mph. If metric speed limit signs are posted km, what will they read? Round to the nearest whole number.
The speed limit on the New York State Thruway is 65 m.p.h, exactly. Considering that 1.00 mi. = 1.61 km, what would the speed limit be in k.p.h. if the United States were to convert to the metric system. Show your work and express your answer to the proper number of significant figures.
