an engineer is converting the speed of a car from kilometers per hour to miles per hour and then to feet per second. if the cars speed is 96 kilometers per hour, what is its speed in feet per second? (note: 1 kilometer is approximately 0.621371 miles, and 1 mile is 5280 feet)

an engineer is converting the speed of a car from kilometers per hour to miles per hour and then to feet per second. if the cars speed is 96 kilometers per hour, what is its speed in feet per second? (note: 1 kilometer is approximately 0.621371 miles, and 1 mile is 5280 feet)

Answer

Explanation:

Step1: Convert km/h to miles/h

We know 1 km = 0.621371 miles. So, if the speed is 96 km/h, then in miles/h, we multiply 96 by 0.621371. $96\times0.621371 = 59.651616$ miles/h

Step2: Convert miles/h to feet/h

Since 1 mile = 5280 feet, we multiply the speed in miles/h by 5280. $59.651616\times5280= 315960.53248$ feet/h

Step3: Convert feet/h to feet/s

There are 3600 seconds in an hour. So we divide the speed in feet/h by 3600. $\frac{315960.53248}{3600}\approx87.77$ feet/s

Answer:

87.77 feet/s
