85 x 45/60 = 63.75 km
118 x 16/60 = 31.47 km
43 x 13/60 = 9.32 km
63.75 + 31.47 + 9.32 = 104.54 km
45 + 16 + 19 + 13 = 93 min = 1.55 hours
104.54 ÷ 1.55 = 67.45 km/h

Answer:
The cold length of metal rod is 435.14 cm
Step-by-step explanation:
Given as :
The percentage expansion of metal rod = 3.5%
The quantity of expansion = 15.23 cm
Let the cold length be x
So, 3. 5% of x = 15.23 cm
Or, 0.035 × x = 15.23 cm
Or, x = cm
∴ x = 435.14 cm
Hence The cold length of metal rod is 435.14 cm Answer
