Question

7. The distance of the earth from the sun is 149000000
km. How long will a sunray take to reach the earth if
it travels at a speed of 3.0 x 10 power 5km/s?
​

Answer 1

Answer:

496.667 sec

Step-by-step explanation:

As,

S=vt

t=s/v

t=149000000/(3×10^5)

t=496.667 sec

Answer 2

$Distance \: = \: 149000000 \: Km \\ Speed \: = \: 3 × {10}^{5} km/s \\ as \: we \: know \\ speed \: = \: Distance \div time \\ Time \: = \: Distance/Speed \\ </p><p>= \: (149000000 \: km)/(3 × 10 \: km/s) \\ </p><p>= \: 496.67 \: seconds \\ \\ : ) \: thankyou$
