Strachan is heading towards Mars at the rate of 7.7 x 10^4 miles per hour if the asteroid is 3.311 x 10^8 miles away from Mars. How many hours will it be before it hits Mars, but the answer and scientific notation express to the exact decimal place

1 answer

To find the time it would take for Strachan to hit Mars, we can use the formula:

Time = Distance / Speed

Given:
Distance = 3.311 x 10^8 miles
Speed = 7.7 x 10^4 miles per hour

Plugging in the values, we get:
Time = (3.311 x 10^8) / (7.7 x 10^4)
Time = 4.2987012987 x 10^3 hours

Rounded to one decimal place, the time it takes for Strachan to hit Mars is approximately 4298.7 hours.
