Correction: Since the question refer to speed instead of velocity, the -ve value must take consideration. Therefore, t1=61.904s, t2=72.763s, t3=99.125s, t4= 109.983s

Clue: 105 more small balloons Therefore, compare the balloons at equal length. Common multiple of 90cm and 120cm is 360cm 90cm = 2 balloons 360cm = 2 x 4 = 8 balloons 1.2m = 120cm 120cm = 5 balloons 360cm = 5 x 3 = 15 balloons In one set, there is a difference of 15 - 8 = 7 balloons For 105 balloons difference, there will be 105 divide by 7 = 15 sets In one set, there are 15 + 8 = 23 balloons Therefore, total balloons 23 x 15 = 345 balloons

You should start with the multiplication first. Then, proceed with the conversion unit. For cm to m conversion, you need to divide by 100, while m to km divide by 1000. b) 10 x 0.085 cm = 0.85cm d) 45 x 10.2 cm = 459 cm = 4.59 m f) 20 x 50 3/4 m = 1015 m = 1.015 km. If you need further clarification, please book for 1-to-1 session with me.
