If they meant 10 sets of push-ups, then she did 45. if they just meant 10 push-ups, it is 25.
Step-by-step explanation:
Distance = Speed x Time
Given Distance = 40km/h or kph
Time = 5 hours 15 minutes
=

Distance Travelled = 40 kph x 5.25 hours
= 210km
I would say 20
I’m not so totally sure but I believe it’s that because of the ratios, CB:CE is 3:6, and then CA:CT would probably be 10:20. does that make sense?
sorry if i’m incorrect
