If you walk 45 minutes at a rate 4km/h and then run for 30 minutes at a rate of 10km/h, how many kilometers will you have gone at the end of one hour and 15 minutes
45minutes=0,75 hour
\(\Rightarrow\)45 minutes we will have gone: 0,75x4= 3(km)
30minutes=0,5hour
\(\Rightarrow\)30 minutes we will have gone: 0,5x10=5(km)
\(\Rightarrow\)we will have gone 8 kms at one hour fifteen minutes
