Answer:
57.78 km/hr
Step-by-step explanation:
Total time taken, t = 6 hours
Total distance covered, d = 520 km
Distance by car = 260
Distance by train = 520 - 260 = 260 km
Train speed = x
Car speed = 2x
Average speed speed = 3x /2
Speed = distance / time
1.5x = 520 / 6
9x = 520
x = 520 / 9
x = 57.777
Average speed of train = 57.78 km/hr
ABC and HJK are congruent and the corresponding sides and angles are equal. Side HJ is congruent with side AB so HJ is also 3.5cm in length.
7.6 - 5(k + 1.1) = 1.6
7.6 - 5(k + 1.1) - 7.6 = 1.6 - 7.6
-5(k +1.1) = -6
-5(k + 1.1) -6
-------------- = ---------
-5 -5
k + 1.1 = 6
-----
5
k + 1.1 - 1.1 = 6
----- - 1.1
