Assume that the speed of light is 300,000 km/s. Find the distance traveled by light in the times given below. Use scientific notation.
a. 15 minutes
b. 1 hour
c. 24 hours
d. 1 year
+23254 a) 15 min = 15 min x 60 s/min = 900 secs
300 000 x 900 = 270 000 000 km = 2.7 x 10^8 km
b) 1 hour = 60 min/hr x 60 s/min = 3600 secs
300 000 x 3600 = 1 080 000 000 km = 1.08 x 10^9 km
c) 24 hours = last answer times 24
d) 1 year = last answer times 365 (approximately; go on-line for a better approximation)
