a car drives 10 1/2 miles in 1/6 hour. what is its speed in miles per hour

Answers

(Credit to guy/girl above) 63 miles 10 1/2 x 6 is 63.

The speed for the given distance and time is 12.6 miles per hour.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a car drives [tex]10\frac{1}{2}[/tex] miles in 1/6 hour.

We know that, the formula to find the speed is Speed=Distance/Time

Speed = [tex]10\frac{1}{2}[/tex] ÷ 1/6

= 21/10 ×6/1

= 63/5

= 12.6 miles per hour

Therefore, the speed for the given distance and time is 12.6 miles per hour.
