Answer:
A
Step-by-step explanation:
Because you have to use the Pythagorean theorem to solve for this.
total distance travelled=72+69=141
time taken in hours for journey= (48/60)h + (69/60)= 1.95 h
average speed=141km/1.95h= 72.3km/h (3 sf)
1000 times cause its the value of the number
10 is your common difference
