He sun is about 93 million miles from the earth. express this distance in scientific notation. a) 0.93 x 108 b) 9.3 x 107 c) 9.3 x 106 d) 93 x 106

B)  9.3 * 10^7.

Step-by-step explanation:

93,000,000

Recall that scientific notation is N.N..  * 10^n  where N.N.. is a number between 1 and 10 and n is an integer.

There are 7 digits after the 9 so the distance in scientific form is

9.3 * 10^7.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: -0.5 would be the most likley outcome
