Peter ran at a speed of 12.4 km/h. After 45 minutes of running, he had a hiatus. The track is 31 km long. How many kilometers is he still to run if he still runs at the same speed?

Correct answer:

x =  21.7 km

Step-by-step explanation:

v=12.4 km/h t=45 min h=45:60  h=0.75 h s=v t=12.4 0.75=1093=9.3 km  s0=31 km  x=s0s=319.3=21.7 km
