Answer:
6.9 x 103
Step-by-step explanation:
Let us say that the variables for flight is designated by
1, while the return flight by 2, since the distance travelled are equal, therefore:
v1 t1 = v2 t2
or
460 t1 = 500 t2
Since t1 + t2 = 4.8, therefore: t1 = 4.8 – t2
460 (4.8 – t2) = 500 t2
2208 – 460 t2 = 500 t2
960 t2 = 2208
t2 = 2.3
t1= 4.8 – t2 = 4.8 – 2.3
t1 = 2.5
Answer:
The flight took 2.5 hours while the return flight took
2.3 hours.
Answer:
452 km is 452,000 meters
Step-by-step explanation:
This question can be solved using a rule of three.
1 km is 1000 meters.
How many meters are 452 km?
1km - 1000m
452km - xm
x = 1000*452
x = 452,000
452 km is 452,000 meters
