Question

How many seconds will it take to drive to San Francisco from Los Angeles if an average speed of 67.0 mi/hr is maintained

Answer 1

Approximately 20525 seconds

Explanation:

Distance between San Francisco and Los Angeles is not given.

Therefore, by using I-5 S, distance between these cities = 381.6

≈ 382 miles

Formula for the average speed is,

Average speed =
`\frac{\text{Distance traveled}}{\text{Time taken}}`

Time taken to reach San Francisco from Los Angeles =
`\frac{\text{Distance traveled}}{\text{Average speed}}`

=
`(382)/(67)`

= 5.702 hours

≈ 5 hours 42 minutes

≈ 342.1 minutes

≈ 20525 seconds
