Answer:
30 hours
Explanation:
Average speed = distance/time
Let the time taken for each plane to pass each other be t
Average speed of plane that left from New York = 650 mph
Distance covered = 650t miles
Average speed of plane that left from Mexico = 550 mph
Distance covered = 550t miles
Distance apart = 3000 miles
650t - 550t = 3000
100t = 3000
t = 3000/100 = 30 hours
Answer:
Explanation:
We also know that, v = S/t which can be rewritten as v * t = S
Where,
v = velocity
S = distance
t = time
i. v1*t = S1
ii. v2*t = S2
iii. s1 + s2 = 3000
Substituting i and ii into equation iii,
St = S1 + S2
v1*t + v2*t = 3000
650*t + 550*t = 3000
1200*t = 3000
t = 3000/1200
t = 2.5 h.
