Answer:
The time required them working together to shovel the snow is T = 1.428 hours
Step-by-step explanation:
Given data
Time taken by first person to shovel the snow = 2 hours
Time taken by second person to shovel the snow = 5 hours
Time taken by both persons to shovel the snow
Put all the values in above equation we get
T = 1.428 hours
Therefore the time required them working together to shovel the snow is T = 1.428 hours
Answer:
11:18
Step-by-step explanation:
Here, we are interested in calculating the ratio of diameter of ball A to that of ball B
what to do here is to ensure that both diameters have measurements that are same units.
Thus, mathematically;
44 mm to 7.2cm
But, mathematically;
10 mm = 1 cm
Thus 7.2cm = 7.2 * 10 = 72mm
Thus, our ratio becomes;
44:72
divide through be 4, we have
44/4 : 72/4
= 11 : 18
