Answer:
No, we will not get there on time.
Step-by-step explanation:
         Abilene   Dallas    El Paso    Lubbock    San Antonio
Abilene     n/a...........  185...............447............ 165................. 261 Â
Dallas       185.............n/a.............. 633.............351................ 277 Â
El Paso      447........... 633...............n/a...............344...............558 Â
Lubbock      165 ............351.............. 344...............n/a................394 Â
San Ant      261............. 277.............. 558............. 394................n/a
Now we are given that: " You are driving from Lubbock to Abilene at 55 mph. You must be there in 2 1/2 hours".
As the Number of miles between Lubbock to Abilene is 165.
And the speed is given to be 55 mph.
So the time taken to reach Abilene is given by:
As we know that time taken= (Distance covered)/(Speed)
Hence time taken=(165)/(55)= Â 3 hours.
Hence we can't reach there on time( i.e. [tex]2\frac{1}{2}hour[/tex])
