Question

Type the correct answer in the box. Use numerals instead of words. Convert miles per hour to meters per second. Round the answer to the nearest whole number. (1 mile = 1,609 meters, 1 hour = 3,600 seconds) 65 miles per hour = meters per second.

Answer 1

Since you're given the number of meters in a mile and seconds in a hour, you have

$\dfrac{1 \text{ mile}}{1 \text{ hour}} = \dfrac{1609\text{ meters}}{3600\text{ seconds}} = \dfrac{1609}{3600} \dfrac{\text{meters}}{\text{seconds}}$

So, 65 miles per hour are equivalent to

$65 \times\dfrac{1609}{3600} \dfrac{\text{meters}}{\text{seconds}} \approx 29 \dfrac{\text{meters}}{\text{seconds}}$
