Question

A student can pitch a fast ball at 65 miles per hour. Convert this

speed to yards per second.
O 95.33 yd/sec
O 132.95 yd/sec
O 31.77 yd/sec
O 21.67 yd/sec

Answer 1

31.77 yd/sec

Step-by-step explanation:

Conversions:

• 1 mile = 1760 yards
• 1 hour = 3600 seconds

Given:

`\sf 65\:miles\:per\:hour=65\:miles/hour=(65\:miles)/(hour)`

Therefore, to convert 65 mph to yards per second:

`\implies \sf (65\:miles)/(hour)=(65 * 1760\:yards)/(3600\:seconds)=31.777...\:yd/s`

Answer 2

c.) 31.77... yd/sec

Step-by-step explanation:

Given: 1 hours → 65 miles

Conversions:

(i) 1 hour = 60 minutes = 3600 seconds

(ii) 1 miles = 1760 yards

Then,

• 1 hour = 3600 seconds

• 65 miles = (1760 × 65) = 114400 yards

Speed:

⇒ distance/speed

⇒ 114400/3600

⇒ 31.77777...

⇒ 31.77 yd/sec
