The time at which the break started is 10 : 30 am.

<h3>What time did the break start?</h3>

The first step is to convert the time between  10:00 a.m. - 11:15 a.m. to minutes.

The time  between  10:00 a.m. - 11:15 a.m. is 1 hour 15 minutes

In order to convert hours to minutes, multiply hour by 60

1 x 60 = 60 minutes

60 minutes +  15 minutes =  75 minutes

The second step is to subtract the time from the break from the duration of the golf lesson

75 minutes -  15 minutes = 60 minutes

The third step is to divide 60 minutes into equal halves by dividing 60 by 2

60 / 2 = 30 minutes

The last step is to add 30 minutes to the time the lesson started : 10 : 00 am + 30 minutes = 10 : 30 am

The average grain of salt is 0.0003 meters wide. Rhinovirus, which causes the common cold, is 0.00000003 meters wide. How many t
algol [13]

Answer:

1\times 10^4\ times

Step-by-step explanation:

Given:

Width of average grain of salt is, w=0.0003\ m

Width of Rhinovirus is, W=0.00000003\ m

Now, expressing each width in scientific notation form, we get:

w=0.0003\ m = 3\times 10^{-4}\ m\\\\W=0.00000003\ m = 3\times 10^{-8}\ m

Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,

\frac{W}{w}=\frac{3\times 10^{-4}\ m}{3\times 10^{-8}\ m}\\\\\frac{W}{w}=1\times 10^{-4-(-8)}=1\times 10^{-4+8}=1\times 10^4\\\\\therefore W=1\times 10^4\times w

Therefore, the grain of salt is 1\times 10^4\ times wider than Rhinovirus.
