Question

A car is traveling at a rate of 25 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 2 hours? Do not round your answers

Answer 1

first convert 25 m into kilometer.
25m=25/1000km=1/40km
and then convert second into minutes i.e., 1sec=1/3600 minutes

Answer 2

\[25 \frac{m}{s} * \frac{1 km}{1000 m}*\frac{3600 s}{1 hr}\]

Answer 3

25m/sec=(1/40)/(1/3600)=3600/40=90km/hr
