Answer 2

Answer:

25 m/s

Step-by-step explanation:

Given,

1 mile = 1609 meters,

Here, rate is 55 miles per hour

That is, number of miles in 1 hour = 55 miles,

⇒ Number of miles in 1 hour = 55 ×  1609 = 88495 meters,

Since, 1 hour = 60 min and 1 min = 60 seconds ⇒ 1 hour = 3600 seconds,

⇒ Number of miles in 3600 sec = 88495 meters,

⇒ Number of miles in 1 sec = $\frac{88495}{3600}$ = 24.58 meter ≈ 25 metre

Thus, 55 mph = 25 meter per sec
